+// This is the base class for implementing dispatchers. We have two concrete
+// dispatcher implementations:
+//
+//   * A NamespaceDispatchInterceptor, which dispatch calls to existing
+//     namespace interceptors
+//   * A DomainDispatchInterceptor, which dispatch calls to existing domain
+//     interceptors.
+//
+// With the JMX Namespaces feature, the JMX MBeanServer is now structured
+// as follows:
+//
+// The JMX MBeanServer delegates to a NamespaceDispatchInterceptor,
+// which either dispatches to a namespace, or delegates to the
+// DomainDispatchInterceptor (if the object name contained no namespace).
+// The DomainDispatchInterceptor in turn either dispatches to a domain (if
+// there is a JMXDomain for that domain) or delegates to the
+// DefaultMBeanServerInterceptor (if there is no JMXDomain for that
+// domain). This makes the following picture:
+//
+//             JMX MBeanServer (outer shell)
+//                          |
+//                          |

+//                /                   dispatch to namespace
+//         DomainDispatchInterceptor

-/**
- * <p>Base class for custom implementations of the {@link MBeanServer}
- * interface. The commonest use of this class is as the {@linkplain
- * JMXNamespace#getSourceServer() source server} for a {@link
- * JMXNamespace}, although this class can be used anywhere an {@code
- * MBeanServer} instance is required. Note that the usual ways to
- * obtain an {@code MBeanServer} instance are either to use {@link
- * java.lang.management.ManagementFactory#getPlatformMBeanServer()
- * ManagementFactory.getPlatformMBeanServer()} or to use the {@code
- * newMBeanServer} or {@code createMBeanServer} methods from {@link
- * javax.management.MBeanServerFactory MBeanServerFactory}. {@code
- * MBeanServerSupport} is for certain cases where those are not
- * appropriate.</p>
- *
- * <p>There are two main use cases for this class: <a
- * href="#special-purpose">special-purpose MBeanServer implementations</a>,
- * and <a href="#virtual">namespaces containing Virtual MBeans</a>. The next
- * sections explain these use cases.</p>
- *
- * <p>In the simplest case, a subclass needs to implement only two methods:</p>
- *
- * <ul>
- *     <li>
- *         {@link #getNames getNames} which returns the name of
- *         all MBeans handled by this {@code MBeanServer}.
- *     </li>
- *     <li>
- *         {@link #getDynamicMBeanFor getDynamicMBeanFor} which returns a
- *         {@link DynamicMBean} that can be used to invoke operations and
- *         obtain meta data (MBeanInfo) on a given MBean.
- *     </li>
- * </ul>
- *
- * <p>Subclasses can create such {@link DynamicMBean} MBeans on the fly - for
- * instance, using the class {@link javax.management.StandardMBean}, just for
- * the duration of an MBeanServer method call.</p>
- *
- * <h4 id="special-purpose">Special-purpose MBeanServer implementations</h4>
- *
- * <p>In some cases
- * the general-purpose {@code MBeanServer} that you get from
- * {@link javax.management.MBeanServerFactory MBeanServerFactory} is not
- * appropriate.  You might need different security checks, or you might
- * want a mock {@code MBeanServer} suitable for use in tests, or you might
- * want a simplified and optimized {@code MBeanServer} for a special purpose.</p>
- *
- * <p>As an example of a special-purpose {@code MBeanServer}, the class {@link
- * javax.management.QueryNotificationFilter QueryNotificationFilter} constructs
- * an {@code MBeanServer} instance every time it filters a notification,
- * with just one MBean that represents the notification. Although it could
- * use {@code MBeanServerFactory.newMBeanServer}, a special-purpose {@code
- * MBeanServer} will be quicker to create, use less memory, and have simpler
- * methods that execute faster.</p>
- *
- * <p>Here is an example of a special-purpose {@code MBeanServer}
- * implementation that contains exactly one MBean, which is specified at the
- * time of creation.</p>
- *
- * <pre>
- * public class SingletonMBeanServer extends MBeanServerSupport {
- *     private final ObjectName objectName;
- *     private final DynamicMBean mbean;
- *
- *     public SingletonMBeanServer(ObjectName objectName, DynamicMBean mbean) {
- *         this.objectName = objectName;
- *         this.mbean = mbean;
- *     }
- *
- *     &#64;Override
- *     protected {@code Set<ObjectName>} {@link #getNames getNames}() {
- *         return Collections.singleton(objectName);
- *     }
- *
- *     &#64;Override
- *     public DynamicMBean {@link #getDynamicMBeanFor
- *                                getDynamicMBeanFor}(ObjectName name)
- *             throws InstanceNotFoundException {
- *         if (objectName.equals(name))
- *             return mbean;
- *         else
- *             throw new InstanceNotFoundException(name);
- *     }
- * }
- * </pre>
- *
- * <p>Using this class, you could make an {@code MBeanServer} that contains
- * a {@link javax.management.timer.Timer Timer} MBean like this:</p>
- *
- * <pre>
- *     Timer timer = new Timer();
- *     DynamicMBean mbean = new {@link javax.management.StandardMBean
- *                                     StandardMBean}(timer, TimerMBean.class);
- *     ObjectName name = new ObjectName("com.example:type=Timer");
- *     MBeanServer timerMBS = new SingletonMBeanServer(name, mbean);
- * </pre>
- *
- * <p>When {@code getDynamicMBeanFor} always returns the same object for the
- * same name, as here, notifications work in the expected way: if the object
- * is a {@link NotificationEmitter} then listeners can be added using
- * {@link MBeanServer#addNotificationListener(ObjectName, NotificationListener,
- * NotificationFilter, Object) MBeanServer.addNotificationListener}.  If
- * {@code getDynamicMBeanFor} does not always return the same object for the
- * same name, more work is needed to make notifications work, as described
- * <a href="#notifs">below</a>.</p>
- *
- * <h4 id="virtual">Namespaces containing Virtual MBeans</h4>
- *
- * <p>Virtual MBeans are MBeans that do not exist as Java objects,
- * except transiently while they are being accessed.  This is useful when
- * there might be very many of them, or when keeping track of their creation
- * and deletion might be expensive or hard.  For example, you might have one
- * MBean per system process.  With an ordinary {@code MBeanServer}, you would
- * have to list the system processes in order to create an MBean object for
- * each one, and you would have to track the arrival and departure of system
- * processes in order to create or delete the corresponding MBeans.  With
- * Virtual MBeans, you only need the MBean for a given process at the exact
- * point where it is referenced with a call such as
- * {@link MBeanServer#getAttribute MBeanServer.getAttribute}.</p>
- *
- * <p>Here is an example of an {@code MBeanServer} implementation that has
- * one MBean for every system property.  The system property {@code "java.home"}
- * is represented by the MBean called {@code
- * com.example:type=Property,name="java.home"}, with an attribute called
- * {@code Value} that is the value of the property.</p>
- *
- * <pre>
- * public interface PropertyMBean {

- * </pre>
- *
- * <p id="virtual-notif-example">Because the {@code getDynamicMBeanFor} method
- * returns a different object every time it is called, the default handling
- * of notifications will not work, as explained <a href="#notifs">below</a>.
- * In this case it does not matter, because the object returned by {@code

- *
- * <h4 id="creation">MBean creation and deletion</h4>
- *
- * <p>MBean creation through {@code MBeanServer.createMBean} is disabled
- * by default. Subclasses which need to support MBean creation
- * through {@code createMBean} need to implement a single method {@link
- * #createMBean(String, ObjectName, ObjectName, Object[], String[],
- * boolean)}.</p>
- *
- * <p>Similarly MBean registration and unregistration through {@code
- * registerMBean} and {@code unregisterMBean} are disabled by default.
- * Subclasses which need to support MBean registration and
- * unregistration will need to implement {@link #registerMBean registerMBean}
- * and {@link #unregisterMBean unregisterMBean}.</p>
- *
- * <h4 id="notifs">Notifications</h4>
- *
- * <p>By default {@link MBeanServer#addNotificationListener(ObjectName,
- * NotificationListener, NotificationFilter, Object) addNotificationListener}
- * is accepted for an MBean <em>{@code name}</em> if {@link #getDynamicMBeanFor
- * getDynamicMBeanFor}<code>(<em>name</em>)</code> returns an object that is a
- * {@link NotificationEmitter}.  That is appropriate if
- * {@code getDynamicMBeanFor}<code>(<em>name</em>)</code> always returns the
- * same object for the same <em>{@code name}</em>.  But with
- * Virtual MBeans, every call to {@code getDynamicMBeanFor} returns a new object,
- * which is discarded as soon as the MBean request has finished.
- * So a listener added to that object would be immediately forgotten.</p>
- *
- * <p>The simplest way for a subclass that defines Virtual MBeans
- * to support notifications is to create a private {@link VirtualEventManager}
- * and override the method {@link
- * #getNotificationEmitterFor getNotificationEmitterFor} as follows:</p>
- *
- * <pre>
- *     private final VirtualEventManager vem = new VirtualEventManager();
- *
- *     &#64;Override
- *     public NotificationEmitter getNotificationEmitterFor(
- *             ObjectName name) throws InstanceNotFoundException {
- *         // Check that the name is a valid Virtual MBean.
- *         // This is the easiest way to do that, but not always the
- *         // most efficient:
- *         getDynamicMBeanFor(name);
- *
- *         // Return an object that supports add/removeNotificationListener
- *         // through the VirtualEventManager.
- *         return vem.getNotificationEmitterFor(name);
- *     }
- * </pre>
- *
- * <p>A notification <em>{@code n}</em> can then be sent from the Virtual MBean
- * called <em>{@code name}</em> by calling {@link VirtualEventManager#publish
- * vem.publish}<code>(<em>name</em>, <em>n</em>)</code>.  See the example
- * <a href="#virtual-notif-example">above</a>.</p>

+
+/**
+ * An object that can rewrite ObjectNames contained in input/output
+ * parameters when entering/leaving a {@link javax.management.namespace
+ * namespace}.
+ * <p>When entering a {@link javax.management.namespace
+ *    namespace}, the {@code namespace} prefix is stripped from
+ *    ObjectNames contained in input parameters. When leaving a
+ *    {@code namespace},
+ *    the {@code namespace} prefix is prepended to the ObjectNames contained in
+ *    the result parameters returned from that {@code namespace}.
+ * </p>
+ * <p>Objects that need to perform these operations usually use a
+ *    {@code RewritingProcessor} for that purpose.<br>
+ *    The {@code RewritingProcessor} allows a somewhat larger
+ *    transformation in which part of a prefix {@link #newRewritingProcessor
+ *    remove} can be replaced by another prefix {@link #newRewritingProcessor
+ *    add}. The transformation described above correspond to the case where
+ *    {@code remove} is the stripped {@link javax.management.namespace
+ *    namespace} prefix (removed when entering the {@code namespace}) and
+ *    {@code add} is the empty String {@code ""}.
+ *    <br>
+ *    It is interesting to note that {@link
+ *    javax.management.JMXNamespaces#narrowToNamespace narrowToNamespace}
+ *    operations use the inverse transformation (that is, {@code remove} is
+ *    the empty String {@code ""} and {@code add} is the {@link
+ *    javax.management.namespace namespace} prefix).
+ *    <br>
+ *    On a more general scale, {@link #rewriteInput rewriteInput} removes
+ *    {@link #newRewritingProcessor remove} and the prepend {@link
+ *     #newRewritingProcessor add}, and {@link #rewriteOutput rewriteOutput}
+ *    does the opposite, removing {@link #newRewritingProcessor add}, and
+ *    then adding {@link #newRewritingProcessor remove}.
+ *    <br>
+ *    An implementation of {@code RewritingProcessor} should make sure that
+ *    <code>rewriteInput(rewriteOutput(x,clp),clp)</code> and
+ *    <code>rewriteOutput(rewriteInput(x,clp),clp)</code> always return
+ *    {@code x} or an exact clone of {@code x}.
+ * </p>
+ * <p>A default implementation of {@code RewritingProcessor} based on
+ * Java Object Serialization can be
+ * obtained from {@link #newRewritingProcessor newRewritingProcessor}.
+ * </p>
+ * <p>
+ * By default, the instances of {@code RewritingProcessor} returned by
+ * {@link #newRewritingProcessor newRewritingProcessor} will rewrite
+ * ObjectNames contained in instances of classes they don't know about by
+ * serializing and then deserializing such object instances. This will
+ * happen even if such instances don't - or can't contain ObjectNames,
+ * because the default implementation of {@code RewritingProcessor} will
+ * not be able to determine whether instances of such classes can/do contain
+ * instance of ObjectNames before serializing/deserializing them.
+ * </p>
+ * <p>If you are using custom classes that the default implementation of
+ * {@code RewritingProcessor} don't know about, it can be interesting to
+ * prevent an instance of {@code RewritingProcessor} to serialize/deserialize
+ * instances of such classes for nothing. In that case, you could customize
+ * the behavior of such a {@code RewritingProcessor} by wrapping it in a
+ * custom subclass of {@code RewritingProcessor} as shown below:
+ * <pre>
+ * public class MyRewritingProcessor extends RewritingProcessor {
+ *      MyRewritingProcessor(String remove, String add) {
+ *          this(RewritingProcessor.newRewritingProcessor(remove,add));
+ *      }
+ *      MyRewritingProcessor(RewritingProcessor delegate) {
+ *          super(delegate);
+ *      }
+ *
+ *  <T> T rewriteInput(T input) {
+ *          if (input == null) return null;
+ *          if (MyClass.equals(input.getClass())) {
+ *              // I know that MyClass doesn't contain any ObjectName
+ *              return (T) input;
+ *          }
+ *          return super.rewriteInput(input);
+ *      }
+ *  <T> T rewriteOutput(T result) {
+ *          if (result == null) return null;
+ *          if (MyClass.equals(result.getClass())) {
+ *              // I know that MyClass doesn't contain any ObjectName
+ *              return (T) result;
+ *          }
+ *          return super.rewriteOutput(result);
+ *      }
+ * }
+ * </pre>
+ * </p>
+ * <p>Such a subclass may also provide an alternate way of rewriting
+ *    custom subclasses for which rewriting is needed - for instance:
+ * <pre>
+ * public class MyRewritingProcessor extends RewritingProcessor {
+ *      MyRewritingProcessor(String remove, String add) {
+ *          this(RewritingProcessor.newRewritingProcessor(remove,add));

+/**
+ * A network channel that supports Internet Protocol (IP) multicasting.
+ *
+ * <p> IP multicasting is the transmission of IP datagrams to members of
+ * a <em>group</em> that is zero or more hosts identified by a single destination
+ * address.
+ *
+ * <p> In the case of a channel to an {@link StandardProtocolFamily#INET IPv4} socket,
+ * the underlying operating system supports <a href="http://www.ietf.org/rfc/rfc2236.txt">
+ * <i>RFC&nbsp;2236: Internet Group Management Protocol, Version 2 (IGMPv2)</i></a>.
+ * It may optionally support source filtering as specified by <a
+ * href="http://www.ietf.org/rfc/rfc3376.txt"> <i>RFC&nbsp;3376: Internet Group
+ * Management Protocol, Version 3 (IGMPv3)</i></a>.
+ * For channels to an {@link StandardProtocolFamily#INET6 IPv6} socket, the equivalent
+ * standards are <a href="http://www.ietf.org/rfc/rfc2710.txt"> <i>RFC&nbsp;2710:
+ * Multicast Listener Discovery (MLD) for IPv6</i></a> and <a
+ * href="http://www.ietf.org/rfc/rfc3810.txt"> <i>RFC&nbsp;3810: Multicast Listener
+ * Discovery Version 2 (MLDv2) for IPv6</i></a>.
+ *
+ * <p> The {@link #join(InetAddress,NetworkInterface)} method is used to
+ * join a group and receive all multicast datagrams sent to the group. A channel
+ * may join several multicast groups and may join the same group on several
+ * {@link NetworkInterface interfaces}. Membership is dropped by invoking the {@link
+ * MembershipKey#drop drop} method on the returned {@link MembershipKey}. If the
+ * underlying platform supports source filtering then the {@link MembershipKey#block
+ * block} and {@link MembershipKey#unblock unblock} methods can be used to block or
+ * unblock multicast datagrams from particular source addresses.
+ *
+ * <p> The {@link #join(InetAddress,NetworkInterface,InetAddress)} method
+ * is used to begin receiving datagrams sent to a group whose source address matches
+ * a given source address. This method throws {@link UnsupportedOperationException}
+ * if the underlying platform does not support source filtering.  Membership is
+ * <em>cumulative</em> and this method may be invoked again with the same group
+ * and interface to allow receiving datagrams from other source addresses. The
+ * method returns a {@link MembershipKey} that represents membership to receive
+ * datagrams from the given source address. Invoking the key's {@link
+ * MembershipKey#drop drop} method drops membership so that datagrams from the
+ * source address can no longer be received.
+ *
+ * <h4>Platform dependencies</h4>
+ *
+ * The multicast implementation is intended to map directly to the native
+ * multicasting facility. Consequently, the following items should be considered
+ * when developing an application that receives IP multicast datagrams:
+ *
+ * <ol>
+ *
+ * <li><p> The creation of the channel should specify the {@link ProtocolFamily}
+ * that corresponds to the address type of the multicast groups that the channel
+ * will join. There is no guarantee that a channel to a socket in one protocol
+ * family can join and receive multicast datagrams when the address of the
+ * multicast group corresponds to another protocol family. For example, it is
+ * implementation specific if a channel to an {@link StandardProtocolFamily#INET6 IPv6}
+ * socket can join an {@link StandardProtocolFamily#INET IPv4} multicast group and receive
+ * multicast datagrams sent to the group. </p></li>
+ *
+ * <li><p> The channel's socket should be bound to the {@link
+ * InetAddress#isAnyLocalAddress wildcard} address. If the socket is bound to
+ * a specific address, rather than the wildcard address then it is implementation
+ * specific if multicast datagrams are received by the socket. </p></li>
+ *
+ * <li><p> The {@link StandardSocketOption#SO_REUSEADDR SO_REUSEADDR} option should be
+ * enabled prior to {@link NetworkChannel#bind binding} the socket. This is
+ * required to allow multiple members of the group to bind to the same
+ * address. </p></li>
+ *
+ * </ol>
+ *
+ * <p> <b>Usage Example:</b>
+ * <pre>
+ *     // join multicast group on this interface, and also use this
+ *     // interface for outgoing multicast datagrams
+ *     NetworkInterface ni = NetworkInterface.getByName("hme0");
+ *
+ *     DatagramChannel dc = DatagramChannel.open(StandardProtocolFamily.INET)
+ *         .setOption(StandardSocketOption.SO_REUSEADDR, true)
+ *         .bind(new InetSocketAddress(5000))
+ *         .setOption(StandardSocketOption.IP_MULTICAST_IF, ni);
+ *
+ *     InetAddress group = InetAddress.getByName("225.4.5.6");
+ *
+ *     MembershipKey key = dc.join(group, ni);

+ * <p> A <i>channel</i> represents an open connection to an entity such as a
+ * hardware device, a file, a network socket, or a program component that is
+ * capable of performing one or more distinct I/O operations, for example reading
+ * or writing.  As specified in the {@link java.nio.channels.Channel} interface,
+ * channels are either open or closed, and they are both <i>asynchronously
+ * closeable</i> and <i>interruptible</i>.
+ *
+ * <p> The {@link java.nio.channels.Channel} interface is extended by several
+ * other interfaces.
+ *
+ * <p> The {@link java.nio.channels.ReadableByteChannel} interface specifies a
+ * {@link java.nio.channels.ReadableByteChannel#read read} method that reads bytes
+ * from the channel into a buffer; similarly, the {@link
+ * java.nio.channels.WritableByteChannel} interface specifies a {@link
+ * java.nio.channels.WritableByteChannel#write write} method that writes bytes
+ * from a buffer to the channel. The {@link java.nio.channels.ByteChannel}
+ * interface unifies these two interfaces for the common case of channels that can
+ * both read and write bytes. The {@link java.nio.channels.SeekableByteChannel}
+ * interface extends the {@code ByteChannel} interface with methods to {@link
+ * java.nio.channels.SeekableByteChannel#position() query} and {@link
+ * java.nio.channels.SeekableByteChannel#position(long) modify} the channel's
+ * current position, and its {@link java.nio.channels.SeekableByteChannel#size
+ * size}.
+ *
+ * <p> The {@link java.nio.channels.ScatteringByteChannel} and {@link
+ * java.nio.channels.GatheringByteChannel} interfaces extend the {@link
+ * java.nio.channels.ReadableByteChannel} and {@link
+ * java.nio.channels.WritableByteChannel} interfaces, respectively, adding {@link
+ * java.nio.channels.ScatteringByteChannel#read read} and {@link
+ * java.nio.channels.GatheringByteChannel#write write} methods that take a
+ * sequence of buffers rather than a single buffer.
+ *
+ * <p> The {@link java.nio.channels.NetworkChannel} interface specifies methods
+ * to {@link java.nio.channels.NetworkChannel#bind bind} the channel's socket,
+ * obtain the address to which the socket is bound, and methods to {@link
+ * java.nio.channels.NetworkChannel#getOption get} and {@link
+ * java.nio.channels.NetworkChannel#setOption set} socket options. The {@link
+ * java.nio.channels.MulticastChannel} interface specifies methods to join
+ * Internet Protocol (IP) multicast groups.
+ *
+ * <p> The {@link java.nio.channels.Channels} utility class defines static methods
+ * that support the interoperation of the stream classes of the <tt>{@link

-
-<p> A <i>channel</i> represents an open connection to an entity such as a
-hardware device, a file, a network socket, or a program component that is
-capable of performing one or more distinct I/O operations, for example reading
-or writing.  As specified in the {@link java.nio.channels.Channel} interface,
-channels are either open or closed, and they are both <i>asynchronously
-closeable</i> and <i>interruptible</i>.
-
-<p> The {@link java.nio.channels.Channel} interface is extended by several
-other interfaces, each of which specifies a new I/O operation.
-
-<p> The {@link java.nio.channels.ReadableByteChannel} interface specifies a
-{@link java.nio.channels.ReadableByteChannel#read read} method that reads bytes
-from the channel into a buffer; similarly, the {@link
-java.nio.channels.WritableByteChannel} interface specifies a {@link
-java.nio.channels.WritableByteChannel#write write} method that writes bytes
-from a buffer to the channel.  The {@link java.nio.channels.ByteChannel}
-interface unifies these two interfaces for the common case of channels that can
-both read and write bytes.
-
-<p> The {@link java.nio.channels.ScatteringByteChannel} and {@link
-java.nio.channels.GatheringByteChannel} interfaces extend the {@link
-java.nio.channels.ReadableByteChannel} and {@link
-java.nio.channels.WritableByteChannel} interfaces, respectively, adding {@link
-java.nio.channels.ScatteringByteChannel#read read} and {@link
-java.nio.channels.GatheringByteChannel#write write} methods that take a
-sequence of buffers rather than a single buffer.
-
-<p> The {@link java.nio.channels.Channels} utility class defines static methods
-that support the interoperation of the stream classes of the <tt>{@link
-java.io}</tt> package with the channel classes of this package.  An appropriate
-channel can be constructed from an {@link java.io.InputStream} or an {@link
-java.io.OutputStream}, and conversely an {@link java.io.InputStream} or an
-{@link java.io.OutputStream} can be constructed from a channel.  A {@link
-java.io.Reader} can be constructed that uses a given charset to decode bytes
-from a given readable byte channel, and conversely a {@link java.io.Writer} can
-be constructed that uses a given charset to encode characters into bytes and
-write them to a given writable byte channel.

-operation creates an instance of the {@link java.nio.MappedByteBuffer}
-class, which extends the {@link java.nio.ByteBuffer} class with several
-file-related operations.
-
-<p> A <tt>getChannel</tt> method has been added to each of the {@link
-java.io.FileInputStream#getChannel FileInputStream}, {@link
-java.io.FileOutputStream#getChannel FileOutputStream}, and {@link
-java.io.RandomAccessFile#getChannel RandomAccessFile} classes of the <tt>{@link
-java.io java.io}</tt> package.  Invoking this method upon an instance of one of
-these classes will return a file channel connected to the underlying file.

+/**
+ * A special {@link JMXNamespace} that can handle part of
+ * the MBeanServer local name space.
+ * <p>
+ * A {@code JMXDomain} makes a domain <i>X</i> of a
+ * {@linkplain #getSourceServer() source MBean server} appear in the same domain
+ * <i>X</i> of a containing {@code MBeanServer} in which the
+ * {@code JMXDomain} MBean {@linkplain #getMBeanServer() is registered}.
+ * </p>
+ * <p>
+ * The JMX infrastructure of the containing {@code MBeanServer} takes care of
+ * routing all calls to MBeans whose names have domain <i>X</i> to the
+ * {@linkplain #getSourceServer() source MBean server} exported by the
+ * {@code JMXDomain} MBean in charge of domain <i>X</i>.
+ * </p>
+ * <p>
+ * The {@linkplain #getSourceServer() source MBean server} of a {@code JMXDomain}
+ * can, but need not be a regular {@code MBeanServer} created through
+ * the {@link javax.management.MBeanServerFactory}. It could also be,
+ * for instance, an instance of a subclass of {@link MBeanServerSupport},
+ * or a custom object implementing the {@link MBeanServer} interface.
+ * </p>
+ *
+ * <h4>Differences between {@code JMXNamespace} and {@code JMXDomain}</h4>
+ *
+ * <p>
+ * A {@code JMXDomain} is a special kind of {@code JMXNamespace}.
+ * A {@code JMXNamespace} such as {@code foo//} is triggered by an
+ * {@code ObjectName} that begins with the string {@code foo//}, for example
+ * {@code foo//bar:type=Baz}.  A {@code JMXDomain} such as {@code foo} is
+ * triggered by an {@code ObjectName} with that exact domain, for example
+ * {@code foo:type=Baz}.  A client can immediately see that an MBean is
+ * handled by a {@code JMXNamespace} because of the {@code //} in the name.
+ * A client cannot see whether a name such as {@code foo:type=Baz} is an
+ * ordinary MBean or is handled by a {@code JMXDomain}.
+ * </p>
+ *
+ * <p>
+ * A {@linkplain MBeanServer#queryNames query} on the containing {@code
+ * MBeanserver} will return all MBeans from the {@code JMXDomain} that match
+ * the query.  In particular, {@code queryNames(null, null)} will return all
+ * MBeans including those from {@code JMXDomain} domains.  On the other hand,
+ * a query will not include MBeans from a {@code JMXNamespace} unless the
+ * {@code ObjectName} pattern in the query starts with the name of that
+ * namespace.
+ * </p>
+ *
+ * <h4 id="security">Permission checks</h4>
+ *
+ * <p>
+ * When a JMXDomain MBean is registered in a containing
+ * MBean server created through the default {@link
+ * javax.management.MBeanServerBuilder}, and if a {@link
+ * SecurityManager SecurityManager} is
+ * {@linkplain System#getSecurityManager() present}, the containing MBeanServer will
+ * check an {@link javax.management.MBeanPermission} before invoking
+ * any method on the {@linkplain #getSourceServer() source MBeanServer} of the
+ * JMXDomain.
+ * </p>
+ *
+ * <p>First, if there is no security manager ({@link
+ * System#getSecurityManager()} is null), that containing
+ * {@code MBeanServer} is free not to make any checks.
+ * </p>
+ *
+ * <p>
+ * Assuming that there is a security manager, or that the
+ * implementation chooses to make checks anyway, the containing
+ * {@code MBeanServer} will perform
+ * {@link javax.management.MBeanPermission MBeanPermission} checks
+ * for access to the MBeans in domain <i>X</i> handled by a {@code JMXDomain}
+ * in the same way that it would do for MBeans registered in its own local
+ * repository, and as <a href="../MBeanServer.html#security">described in
+ * the MBeanServer interface</a>, with the following exceptions:
+ * </p>
+ *
+ * <p>
+ * For those permissions that require a {@code className}, the
+ * <code>className</code> is the
+ * string returned by {@link #getSourceServer() getSourceServer()}.
+ * {@link MBeanServer#getObjectInstance(ObjectName)
+ * getObjectInstance(mbeanName)}.
+ * {@link javax.management.ObjectInstance#getClassName() getClassName()},
+ * except for {@code createMBean} and {@code registerMBean} operations,
+ * for which the permission checks are performed as follows:
+ * </p>
+ * <ul>
+ * <li><p>For {@code createMBean} operations, the {@code className} of the
+ * permission you need is the {@code className} passed as first parameter
+ * to {@code createMBean}.</p>
+ *
+ * <li><p>For {@code registerMBean} operations, the {@code className} of the
+ * permission you need is the name of the class of the mbean object, as
+ * returned by {@code mbean.getClass().getClassName()}, where
+ * {@code mbean} is the mbean reference passed as first parameter
+ * to {@code registerMBean}.</p>
+ *
+ * <li><p>In addition, for {@code createMBean} and {@code registerMBean}, the
+ * permission you need is checked with the {@linkplain ObjectName object name} of
+ * the mbean that is passed as second parameter to the {@code createMBean} or
+ * {@code registerMBean} operation.
+ * </p>
+ *
+ * <li><p>Contrarily to what is done for regular MBeans registered in the
+ *     MBeanServer local repository, the containing MBeanServer will not
+ *     check the {@link javax.management.MBeanTrustPermission#MBeanTrustPermission(String)
+ *     MBeanTrustPermission("register")} against the protection domain
+ *     of the MBean's class. This check can be performed by the
+ *     {@linkplain #getSourceServer source MBean server} implementation,
+ *     if necessary.
+ * </p>
+ * </ul>
+ *
+ * <p>If a security check fails, the method throws {@link
+ * SecurityException}.</p>
+ *
+ * <p>For methods that can throw {@link InstanceNotFoundException},
+ * this exception is thrown for a non-existent MBean, regardless of
+ * permissions.  This is because a non-existent MBean has no
+ * <code>className</code>.</p>
+ *
+ * All these checks are performed by the containing {@code MBeanServer},
+ * before accessing the JMXDomain {@linkplain #getSourceServer source MBean server}.
+ * The implementation of the JMXDomain {@linkplain #getSourceServer source MBean
+ * server} is free to make any additional checks. In fact, if the JMXDomain
+ * {@linkplain #getSourceServer source MBean server} is an {@code MBeanServer}
+ * obtained through the {@link javax.management.MBeanServerFactory}, it will
+ * again make permission checks as described in the
+ * <a href="../MBeanServer.html#security">MBeanServer</a> interface.
+ *
+ * <p>See the <a href="../MBeanServer.html#security">MBeanServer</a> interface
+ * for more details on permission checks.</p>

+/**
+ * MBean Servers can be federated into a single hierarchical name space:
+ * A JMXNamespace is an MBean that handles a sub name space in that
+ * hierarchical name space.
+ * <p>
+ * A name space is created simply by registering a {@code JMXNamespace}
+ * MBean in the MBean Server. The name of the created name space is defined
+ * by the {@linkplain JMXNamespaces#getNamespaceObjectName name of the JMXNamespace}
+ * that handles it. A name space is equivalent to
+ * an MBean Server within an MBean Server. When creating a {@code JMXNamespace},
+ * the MBean Server within is passed to the constructor.
+ * </p>
+ * <p>
+ * The {@code JMXNamespace} class is the base class for implementing
+ * all name space handlers. All name space handlers must be instances of
+ * {@code JMXNamespace} or a subclass of it.
+ * </p>
+ * <p>
+ * A concrete example of a {@code JMXNamespace} MBean subclass
+ * is the {@link JMXRemoteNamespace JMXRemoteNamespace} MBean which
+ * is able to mirror all MBeans contained in a remote MBean server known by its
+ * {@link javax.management.remote.JMXServiceURL}.
+ * </p>
+ * <p>
+ * You can create a local namespace by supplying a newly created MBean Server
+ * to an instance of {@code JMXNamespace}. For instance:
+ * <pre>
+ * final String namespace = "foo";
+ * final ObjectName namespaceName = {@link JMXNamespaces#getNamespaceObjectName
+ *       JMXNamespaces.getNamespaceObjectName(namespace)};
+ * server.registerMBean(new JMXNamespace(MBeanServerFactory.newMBeanServer()),
+ *                      namespaceName);
+ * </pre>
+ * </p>
+ * <p>
+ * <u>Note:</u> A JMXNamespace MBean cannot be registered
+ * simultaneously in two different
+ * MBean servers, or indeed in the same MBean Server with two
+ * different names. It is however possible to give the same MBeanServer
+ * instance to two different JMXNamespace MBeans, and thus create a graph
+ * rather than a tree.
+ * </p>
+ *
+ * <p>To view the content of a namespace, you will usually use an
+ *    instance of {@link JMXNamespaceView}. For instance, given the
+ *    namespace {@code "foo"} created above, you would do:
+ * </p>
+ * <pre>
+ * final JMXNamespaceView view = new JMXNamespaceView(server);
+ * System.out.println("List of namespaces: "+Arrays.toString({@link JMXNamespaceView#list() view.list()}));
+ *
+ * final JMXNamespaceView foo  = {@link JMXNamespaceView#down view.down("foo")};
+ * System.out.println({@link JMXNamespaceView#where() foo.where()}+" contains: " +
+ *        {@link JMXNamespaceView#getMBeanServerConnection foo.getMBeanServerConnection()}.queryNames(null,null));
+ * </pre>
+ *
+ * <h2 id="PermissionChecks">JMX Namespace Permission Checks</h2>
+ *
+ * <p>A special {@link JMXNamespacePermission} is defined to check access
+ * to MBean within namespaces.</p>
+ * <p>When a JMXNamespace MBean is registered in an
+ * MBean server created through the default {@link
+ * javax.management.MBeanServerBuilder}, and if a {@link
+ * SecurityManager SecurityManager} is
+ * {@linkplain System#getSecurityManager() present}, the MBeanServer will
+ * check a {@link JMXNamespacePermission} before invoking
+ * any method on the {@linkplain #getSourceServer source MBeanServer} of the
+ * JMXNamespace.
+ * {@linkplain JMXNamespacePermission JMX Namespace Permissions} are similar to
+ * {@linkplain javax.management.MBeanPermission MBean Permissions}, except
+ * that you usually cannot specify an MBean class name. You can however
+ * specify object name patterns - which will allow you for example to only grant
+ * permissions for MBeans having a specific {@code type=<MBeanType>} key
+ * in their object name.
+ * <p>
+ * Another difference is that {@link JMXNamespacePermission
+ * JMXNamespacePermission} also specifies from which namespace and which
+ * MBean server the permission is granted.
+ * </p>
+ * <p>In the rest of this document, the following terms are used:</p>
+ * <ul>
+ *    <li id="MBeanServerName"><p>{@code server name} is the
+ *    <a href="../MBeanServerFactory.html#MBeanServerName">name of the
+ *    MBeanServer</a> in which the permission is granted.
+ *    The name of an {@code MBeanServer} can be obtained by calling {@link
+ *    javax.management.MBeanServerFactory#getMBeanServerName
+ *    MBeanServerFactory.getMBeanServerName(mbeanServer)}
+ *    </p>
+ *    <li id="NamespaceName"><p>{@code namespace} is the name of the namespace
+ *    in the <a href="#MBeanServerName">named MBean server</a> for which the
+ *    permission is granted. It doesn't contain any
+ *    {@link JMXNamespaces#NAMESPACE_SEPARATOR namespace separator}.
+ *    </p>
+ *    <li id="MBeanName"><p>{@code mbean} is the name
+ *    of the MBean in that {@code namespace}. This is the name of the MBean
+ *    in the namespace's {@link JMXNamespace#getSourceServer() source mbean server}.
+ *    It might contain no, one, or several {@link
+ *    JMXNamespaces#NAMESPACE_SEPARATOR namespace separators}.
+ *    </p>
+ * </ul>
+ *
+ * <p>For instance let's assume that some piece of code calls:</p>
+ * <pre>
+ *     final MBeanServer mbeanServer = ...;
+ *     final ObjectName  name   = new ObjectName("a//b//c//D:k=v");
+ *     mbeanServer.getAttribute(name,"Foo");
+ * </pre>
+ * <p>
+ *   Assuming that there is a security manager, or that the
+ *   implementation chooses to make checks anyway, the checks that will
+ *   be made in that case are:
+ * </p>
+ * <ol>
+ * <li id="check1">
+ * <code>JMXNamespacePermission(mbeanServerName, "Foo", "<b>a//</b>b//c//D:k=v",
+ * "getAttribute")</code>
+ * (where {@code mbeanServerName=MBeanServerFactory.getMBeanServerName(mbeanServer)},
+ * <code>namespace="<b>a</b>"</code>, and {@code mbean="b//c//D:k=v"})
+ * </li>
+ * <li id="check2">and in addition if namespace {@code "a"} is local,
+ * <code>JMXNamespacePermission(aSourceServerName,"Foo","<b>b//</b>c//D:k=v",
+ *       "getAttribute")}</code>
+ * (where
+ * {@code aSourceServerName=MBeanServerFactory.getMBeanServerName(sourceServer(a))},
+ * <code>namespace="<b>b</b>"</code>, and {@code mbean="c//D:k=v"}),
+ * </li>
+ * <li id="check3">and in addition if namespace {@code "b"} is also local,
+ * <code>JMXNamespacePermission(bSourceServerName,"Foo","<b>c//</b>D:k=v",
+ *       "getAttribute")}</code>
+ * (where
+ * {@code bSourceServerName=MBeanServerFactory.getMBeanServerName(sourceServer(b))},
+ * <code>namespace="<b>c</b>"</code>, and {@code mbean="D:k=v"}),
+ * </li>
+ * <li id="check4">and in addition if the source mbean server of namespace
+ * {@code "c"} is a also a local MBeanServer in this JVM,
+ * {@code MBeanPermission(cSourceServerName,<className(D:k=v)>,"Foo","D:k=v","getAttrinute")},
+ * (where
+ * {@code cSourceServerName=MBeanServerFactory.getMBeanServerName(sourceServer(c))}).
+ * </li>
+ * </ol>
+ * <p>For any of these MBean servers, if no name was supplied when
+ * creating that MBeanServer the {@link JMXNamespacePermission} is
+ * created with an {@code mbeanServerName} equal to
+ * {@value javax.management.MBeanServerFactory#DEFAULT_MBEANSERVER_NAME}.
+ * </p>
+ * <p>If the namespace {@code a} is in fact a remote {@code MBeanServer},
+ *    for instance because namespace {@code a} is implemented by a {@link
+ *    JMXRemoteNamespace} pointing to a distant MBeanServer located in
+ *    another JMX agent, then checks <a href="#check2">2</a>,
+ *    <a href="#check3">3</a>, and <a href="#check4">4</a> will not
+ *    be performed in the local JVM. They might or might not be performed in
+ *    the remote agent, depending on how access control and permission
+ *    checking are configured in the remote agent, and how authentication
+ *    is configured in the connector used by the {@link
+ *    JMXRemoteNamespace}.
+ * </p>
+ * <p>In all cases, {@linkplain JMXNamespacePermission JMX Namespace Permissions}
+ * are checked as follows:</p>
+ * <p>First, if there is no security manager ({@link
+ * System#getSecurityManager()} is null), then an implementation of
+ * of MBeanServer that supports JMX namespaces is free not to make any
+ * checks.</p>
+ *
+ * <p>Assuming that there is a security manager, or that the
+ * implementation chooses to make checks anyway, the checks are made
+ * as detailed below.</p>
+ *
+ * <p>If a security check fails, the method throws {@link
+ * SecurityException}.</p>

+/**
+ * <p>A permission controlling access to MBeans located in namespaces.
+ * If a security manager has been set using {@link
+ * System#setSecurityManager}, most operations on an MBean mounted in a
+ * namespace require that the caller's permissions imply a
+ * JMXNamespacePermission appropriate for the operation.
+ * This is described in detail in the
+ * documentation for the
+ * <a href="JMXNamespace.html#PermissionChecks">JMXNamespace</a>
+ * class.</p>
+ *
+ * <p>As with other {@link Permission} objects,
+ * a JMXNamespacePermission can represent either a permission that
+ * you <em>have</em> or a permission that you <em>need</em>.
+ * When a sensitive operation is being checked for permission,
+ * a JMXNamespacePermission is constructed
+ * representing the permission you need.  The operation is only
+ * allowed if the permissions you have {@linkplain #implies imply} the
+ * permission you need.</p>
+ *
+ * <p>A JMXNamespacePermission contains four items of information:</p>
+ *
+ * <ul>
+ *
+ * <li id="Action"><p>The <em>action</em>.</p>
+ * <p>For a permission you need,
+ * this is one of the actions in the list <a
+ * href="#action-list">below</a>.  For a permission you have, this is
+ * a comma-separated list of those actions, or <code>*</code>,
+ * representing all actions.</p>
+ *
+ * <p>The action is returned by {@link #getActions()}.</p>
+ *
+ * <li id="MBeanServerName"><p>The <em>MBean Server name</em>.</p>
+ *
+ * <p>For a permission you need, this is the {@linkplain
+ * javax.management.MBeanServerFactory#getMBeanServerName
+ * name of the MBeanServer}
+ * from which the <a href="#MBeanName">MBean</a> is accessed.</p>
+ *
+ * <p>For a permission you have, this is either the  {@linkplain
+ * javax.management.MBeanServerFactory#getMBeanServerName
+ * name of the MBeanServer} from which the <a href="#MBeanName">MBean</a>
+ * for which you have this permission is accessed,
+ * or a pattern against which that MBean Server name will be matched.<br>
+ * An {@code mbeanServername} pattern can also be empty, or the single
+ * character {@code "*"}, both of which match any {@code MBeanServer} name.
+ * The string {@code "-"} doesn't match any MBeanServer name.
+ * </p>
+ *
+ * <p>Example:</p>
+ * <pre>
+ *   // grant permission to invoke the operation "stop" on any MBean
+ *   // whose name matches "a//*&#42;//*:type=JMXConnectorServer" when
+ *   // accessed from any MBeanServer whose name matches myapp.*"
+ *   permission javax.management.namespace.JMXNamespacePermission "myapp.*::stop[a//*&#42;//*:type=JMXConnectorServer]", "invoke";
+ * </pre>
+ *
+ * <li id="Member"><p>The <em>member</em>.</p>
+ *
+ * <p>For a permission you need, this is the name of the attribute or
+ * operation you are accessing.  For operations that do not reference
+ * an attribute or operation, the member is null.</p>
+ *
+ * <p>For a permission you have, this is either the name of an attribute
+ * or operation you can access, or it is empty or the single character
+ * "<code>*</code>", both of which grant access to any member.</p>
+ *
+ * <p>There is a special case for actions {@code registerMBean} and
+ *    {@code instantiate}, where for a permission you need, {@code member}
+ *    indicates the name of the class for which you are trying
+ *    to create, instantiate, or register an MBean instance. For a
+ *    permission you have, it is a pattern that will be matched against
+ *    the full class name of the MBean being created, instantiated, or
+ *    registered.
+ * </p>
+ *
+ *
+ * <li id="MBeanName"><p>The <em>object name</em>.</p>
+ *
+ * <p>For a permission you need, this is the {@link ObjectName} of the
+ * MBean you are accessing. It is of the form {@code <namespace>//<mbean name>}
+ * where {@code <namespace>} is the name of the name space for which the
+ * permission is checked, and {@code <mbean name>} is the name of the MBean
+ * within that namespace.
+ * <br>
+ * For operations that do not reference a
+ * single MBean, the <em>object name</em> is null.  It is never an object
+ * name pattern.
+ * </p>
+ *
+ * <p>For a permission you have, this is the {@link ObjectName} of the
+ * MBean or MBeans you can access. It is of the form
+ * {@code <namespace>//<mbean name>}
+ * where {@code <namespace>} is the name of the name space for which the
+ * permission is checked, and
+ * {@code <mbean name>} is the name of the MBean
+ * within that namespace. Both {@code <namespace>} and {@code <mbean name>}
+ * can be patterns. The <em>object name</em>
+ * may also be empty, which grants access to all MBeans whatever their
+ * name and namespace.
+ * When included in a namespace path the special path element
+ * <code>**</code> matches any number of sub namespaces
+ * recursively, but only if used as a complete namespace path element,
+ * as in <code>*&#42;//b//c//D:k=v</code> or <code>a//*&#42;//c//D:k=v</code>
+ * - see <a href="#metawildcard">below</a>.
+ * </p>
+ *
+ *
+ * </ul>
+ *
+ * <p>If you have a JMXNamespacePermission, it allows operations only
+ * if all four of the items match.</p>
+ *
+ * <p>The <a href="#MBeanServerName">MBeanServer name</a>,
+ * <a href="#Member">member</a>, and <a href="#MBeanName">object name</a>
+ * can be written together
+ * as a single string, which is the <em>name</em> of this permission.
+ * The name of the permission is the string returned by {@link
+ * java.security.Permission#getName() getName()}.
+ * The format of the string is:</p>
+ *
+ * <blockquote>
+ * {@code <mbean server name>::<member>[<namespace>//<mbean name>]}
+ * </blockquote>
+ *
+ * <p>
+ * The {@code <mbean server name>} is optional. If omitted, {@code "*"} is
+ * assumed, and these three permission names
+ * are thus equivalent:
+ * </p>
+ * <blockquote>
+ * {@code *::<member>[<namespace>//<mbean name>]}<br>
+ * {@code ::<member>[<namespace>//<mbean name>]}<br>
+ * {@code <member>[<namespace>//<mbean name>]}<br>
+ * </blockquote>
+ * <p>
+ *    The {@code <namespace>//<mbean name>} string can be in the form
+ *    of a traditional ObjectName
+ *    pattern - meaning that <code>?</code> will match any single
+ *    character, and <code>*</code> will match any sequence of characters,
+ *    except {@value
+ *    javax.management.namespace.JMXNamespaces#NAMESPACE_SEPARATOR}
+ *    In addition, when included in a namespace path the special
+ *    path element <code>**</code> matches any number of sub namespaces
+ *    recursively.
+ *    A {@code <namespace>//<mbean name>} string of the form
+ *    <code>*&#42;//*:*</code> thus means that the permission is
+ *    granted for all MBeans in all namespaces, recursively (see
+ *    <a href="#metawildcard">below</a> for more details.
+ * </p>
+ * <p>Namespace permission checking may be tricky to configure, depending
+ *    on whether the namespaces crossed to reach the MBean are local or
+ *    remote.<br>
+ *    For instance, let <code>a//b//D:k=v</code> be an MBean exposing an
+ *    attribute <code>Foo</code>.
+ *    If namespace <code>a</code> is a plain JMXNamespace pointing to
+ *    a local MBeanServer in the same JVM, then the permissions you need
+ *    to get the attribute <code>Foo</code> will be:
+ * </p>
+ * <pre>
+ *    // granting permission to access attribute 'Foo' of MBean a//b//D:k=v
+ *    // from MBeanServer named 'srv1'
+ *    // This permission will be checked by the MBeanServer that contains 'a'.
+ *    srv1::Foo[a//b//D:k=v]
+ *
+ *    // Since a is local, you also need the following additional permission,
+ *    // which will be checked by the MBeanServer 'srv2' that contains 'b':
+ *    //
+ *    // granting permission to access attribute 'Foo' of MBean b//D:k=v from
+ *    // 'srv2'
+ *    srv2::Foo[b//D:k=v]
+ * </pre>
+ * <p>On the other hand, if namespace <code>a</code> is a JMXRemoteNamespace
+ *    pointing to an MBeanServer in a remote JVM, then the only permission you
+ *    need to get the attribute <code>Foo</code> will be:
+ * </p>
+ * <pre>
+ *    // granting permission to access attribute 'Foo' of MBean a//b//D:k=v
+ *    // from 'srv1'
+ *    srv1::Foo[a//b//D:k=v]
+ * </pre>
+ * <p>The namespace <code>b</code> resides in the remote JVM, and
+ *    therefore the permissions concerning access to MBeans from
+ *    namespace 'b' will only be checked in the remote JVM, if that JVM is
+ *    configured to do so.
+ * </p>
+ *
+ * <p>The {@code <mbean name>} is written using the usual syntax for {@link
+ * ObjectName}.  It may contain any legal characters, including
+ * <code>]</code>.  It is terminated by a <code>]</code> character
+ * that is the last character in the string.
+ * </p>
+ * <p>Below are some examples of permission names:</p>
+ * <pre>
+ *    // allows access to Foo in 'a//b//*:*' from any MBeanServer in the JVM.
+ *    Foo[a//b//*:*]
+ *
+ *    // allows access to Foo in all subnamespaces of 'a//b', but only for
+ *    // MBeanServers whose name matches 'myapp.*'
+ *    myapp.*::Foo[a//b//*&#42;//*:*]
+ *
+ *    // allows access to Foo from all namespaces in the MBeanServer named
+ *    // 'myapp.srv1' - but not recursively.
+ *    myapp.srv1::Foo[&#42;//*:*]

+ * when the value of its {@link #isConnected Connected} attribute changes.
+ * </p>
+ * <p>
+ * The JMX Remote Namespace MBean is not connected until {@link
+ * #connect() connect()} is explicitly called. The usual sequence of code to
+ * create a JMX Remote Namespace is thus:
+ * </p>
+ * <pre>
+ *     final String namespace = "mynamespace";
+ *     final ObjectName name = {@link JMXNamespaces#getNamespaceObjectName
+ *       JMXNamespaces.getNamespaceObjectName(namespace)};

+ * </pre>
+ * <p>
+ * The JMX Remote Namespace MBean will register for {@linkplain
+ * JMXConnectionNotification JMX Connection Notifications} with its underlying
+ * {@link JMXConnector}. When a JMX Connection Notification indicates that
+ * the underlying connection has failed, the JMX Remote Namespace MBean
+ * closes its underlying connector and switches its {@link #isConnected
+ * Connected} attribute to false, emitting an {@link
+ * AttributeChangeNotification}.
+ * </p>
+ * <p>
+ * At this point, a managing application (or an administrator connected
+ * through a management console) can attempt to reconnect the
+ * JMX Remote Namespace MBean by calling its {@link #connect() connect()} method
+ * again.
+ * </p>
+ * <p>Note that when the connection with the remote namespace fails, or when
+ *    {@link #close} is called, then any notification subscription to
+ *    MBeans registered in that namespace will be lost - unless a custom
+ *    {@linkplain javax.management.event event service} supporting connection-less

+/**
+ * <p>Base class for custom implementations of the {@link MBeanServer}
+ * interface. The commonest use of this class is as the {@linkplain
+ * JMXNamespace#getSourceServer() source server} for a {@link
+ * JMXNamespace}, although this class can be used anywhere an {@code
+ * MBeanServer} instance is required. Note that the usual ways to
+ * obtain an {@code MBeanServer} instance are either to use {@link
+ * java.lang.management.ManagementFactory#getPlatformMBeanServer()
+ * ManagementFactory.getPlatformMBeanServer()} or to use the {@code
+ * newMBeanServer} or {@code createMBeanServer} methods from {@link
+ * javax.management.MBeanServerFactory MBeanServerFactory}. {@code
+ * MBeanServerSupport} is for certain cases where those are not
+ * appropriate.</p>
+ *
+ * <p>There are two main use cases for this class: <a
+ * href="#special-purpose">special-purpose MBeanServer implementations</a>,
+ * and <a href="#virtual">namespaces containing Virtual MBeans</a>. The next
+ * sections explain these use cases.</p>
+ *
+ * <p>In the simplest case, a subclass needs to implement only two methods:</p>
+ *
+ * <ul>
+ *     <li>
+ *         {@link #getNames getNames} which returns the name of
+ *         all MBeans handled by this {@code MBeanServer}.
+ *     </li>
+ *     <li>
+ *         {@link #getDynamicMBeanFor getDynamicMBeanFor} which returns a
+ *         {@link DynamicMBean} that can be used to invoke operations and
+ *         obtain meta data (MBeanInfo) on a given MBean.
+ *     </li>
+ * </ul>
+ *
+ * <p>Subclasses can create such {@link DynamicMBean} MBeans on the fly - for
+ * instance, using the class {@link javax.management.StandardMBean}, just for
+ * the duration of an MBeanServer method call.</p>
+ *
+ * <h4 id="special-purpose">Special-purpose MBeanServer implementations</h4>
+ *
+ * <p>In some cases
+ * the general-purpose {@code MBeanServer} that you get from
+ * {@link javax.management.MBeanServerFactory MBeanServerFactory} is not
+ * appropriate.  You might need different security checks, or you might
+ * want a mock {@code MBeanServer} suitable for use in tests, or you might
+ * want a simplified and optimized {@code MBeanServer} for a special purpose.</p>
+ *
+ * <p>As an example of a special-purpose {@code MBeanServer}, the class {@link
+ * javax.management.QueryNotificationFilter QueryNotificationFilter} constructs
+ * an {@code MBeanServer} instance every time it filters a notification,
+ * with just one MBean that represents the notification. Although it could
+ * use {@code MBeanServerFactory.newMBeanServer}, a special-purpose {@code
+ * MBeanServer} will be quicker to create, use less memory, and have simpler
+ * methods that execute faster.</p>
+ *
+ * <p>Here is an example of a special-purpose {@code MBeanServer}
+ * implementation that contains exactly one MBean, which is specified at the
+ * time of creation.</p>
+ *
+ * <pre>
+ * public class SingletonMBeanServer extends MBeanServerSupport {
+ *     private final ObjectName objectName;
+ *     private final DynamicMBean mbean;
+ *
+ *     public SingletonMBeanServer(ObjectName objectName, DynamicMBean mbean) {
+ *         this.objectName = objectName;
+ *         this.mbean = mbean;
+ *     }
+ *
+ *     &#64;Override
+ *     protected {@code Set<ObjectName>} {@link #getNames getNames}() {
+ *         return Collections.singleton(objectName);
+ *     }
+ *
+ *     &#64;Override
+ *     public DynamicMBean {@link #getDynamicMBeanFor
+ *                                getDynamicMBeanFor}(ObjectName name)
+ *             throws InstanceNotFoundException {
+ *         if (objectName.equals(name))
+ *             return mbean;
+ *         else
+ *             throw new InstanceNotFoundException(name);
+ *     }
+ * }
+ * </pre>
+ *
+ * <p>Using this class, you could make an {@code MBeanServer} that contains
+ * a {@link javax.management.timer.Timer Timer} MBean like this:</p>
+ *
+ * <pre>
+ *     Timer timer = new Timer();
+ *     DynamicMBean mbean = new {@link javax.management.StandardMBean
+ *                                     StandardMBean}(timer, TimerMBean.class);
+ *     ObjectName name = new ObjectName("com.example:type=Timer");
+ *     MBeanServer timerMBS = new SingletonMBeanServer(name, mbean);
+ * </pre>
+ *
+ * <p>When {@code getDynamicMBeanFor} always returns the same object for the
+ * same name, as here, notifications work in the expected way: if the object
+ * is a {@link NotificationEmitter} then listeners can be added using
+ * {@link MBeanServer#addNotificationListener(ObjectName, NotificationListener,
+ * NotificationFilter, Object) MBeanServer.addNotificationListener}.  If
+ * {@code getDynamicMBeanFor} does not always return the same object for the
+ * same name, more work is needed to make notifications work, as described
+ * <a href="#notifs">below</a>.</p>
+ *
+ * <h4 id="virtual">Namespaces containing Virtual MBeans</h4>
+ *
+ * <p>Virtual MBeans are MBeans that do not exist as Java objects,
+ * except transiently while they are being accessed.  This is useful when
+ * there might be very many of them, or when keeping track of their creation
+ * and deletion might be expensive or hard.  For example, you might have one
+ * MBean per system process.  With an ordinary {@code MBeanServer}, you would
+ * have to list the system processes in order to create an MBean object for
+ * each one, and you would have to track the arrival and departure of system
+ * processes in order to create or delete the corresponding MBeans.  With
+ * Virtual MBeans, you only need the MBean for a given process at the exact
+ * point where it is referenced with a call such as
+ * {@link MBeanServer#getAttribute MBeanServer.getAttribute}.</p>
+ *
+ * <p>Here is an example of an {@code MBeanServer} implementation that has
+ * one MBean for every system property.  The system property {@code "java.home"}
+ * is represented by the MBean called {@code
+ * com.example:type=Property,name="java.home"}, with an attribute called
+ * {@code Value} that is the value of the property.</p>
+ *
+ * <pre>
+ * public interface PropertyMBean {
+ *     public String getValue();
+ * }
+ *
+ * <a name="PropsMBS"></a>public class PropsMBS extends MBeanServerSupport {
+ *     private static ObjectName newObjectName(String name) {
+ *         try {
+ *             return new ObjectName(name);
+ *         } catch (MalformedObjectNameException e) {
+ *             throw new AssertionError(e);
+ *         }
+ *     }
+ *
+ *     public static class PropertyImpl implements PropertyMBean {
+ *         private final String name;
+ *
+ *         public PropertyImpl(String name) {
+ *             this.name = name;
+ *         }
+ *
+ *         public String getValue() {
+ *             return System.getProperty(name);
+ *         }
+ *     }
+ *
+ *     &#64;Override

+ *         String propName = ObjectName.unquote(name.getKeyProperty("name"));
+ *         if (System.getProperty(propName) == null)
+ *             throw new InstanceNotFoundException(name);
+ *
+ *         // Construct and return a transient MBean object
+ *         PropertyMBean propMBean = new PropertyImpl(propName);
+ *         return new StandardMBean(propMBean, PropertyMBean.class, false);
+ *     }

+ *         Properties props = System.getProperties();
+ *         for (String propName : props.stringPropertyNames()) {
+ *             ObjectName objectName = newObjectName(
+ *                     "com.example:type=Property,name=" +
+ *                     ObjectName.quote(propName));
+ *             names.add(objectName);
+ *         }
+ *         return names;
+ *     }
+ * }
+ * </pre>
+ *
+ * <p id="virtual-notif-example">Because the {@code getDynamicMBeanFor} method
+ * returns a different object every time it is called, the default handling
+ * of notifications will not work, as explained <a href="#notifs">below</a>.
+ * In this case it does not matter, because the object returned by {@code
+ * getDynamicMBeanFor} is not a {@code NotificationEmitter}, so {@link
+ * MBeanServer#addNotificationListener(ObjectName, NotificationListener,
+ * NotificationFilter, Object) MBeanServer.addNotificationListener} will
+ * always fail. But if we wanted to extend {@code PropsMBS} so that the MBean
+ * for property {@code "foo"} emitted a notification every time that property
+ * changed, we would need to do it as shown below. (Because there is no API to
+ * be informed when a property changes, this code assumes that some other code
+ * calls the {@code propertyChanged} method every time a property changes.)</p>

+ *
+ *     public void propertyChanged(String name, String newValue) {
+ *         ObjectName objectName = newObjectName(
+ *                 "com.example:type=Property,name=" + ObjectName.quote(name));
+ *         Notification n = new Notification(
+ *                 "com.example.property.changed", objectName, 0L,

+ * </pre>
+ *
+ * <h4 id="creation">MBean creation and deletion</h4>
+ *
+ * <p>MBean creation through {@code MBeanServer.createMBean} is disabled
+ * by default. Subclasses which need to support MBean creation
+ * through {@code createMBean} need to implement a single method {@link
+ * #createMBean(String, ObjectName, ObjectName, Object[], String[],
+ * boolean)}.</p>
+ *
+ * <p>Similarly MBean registration and unregistration through {@code
+ * registerMBean} and {@code unregisterMBean} are disabled by default.
+ * Subclasses which need to support MBean registration and
+ * unregistration will need to implement {@link #registerMBean registerMBean}
+ * and {@link #unregisterMBean unregisterMBean}.</p>
+ *
+ * <h4 id="notifs">Notifications</h4>
+ *
+ * <p>By default {@link MBeanServer#addNotificationListener(ObjectName,
+ * NotificationListener, NotificationFilter, Object) addNotificationListener}
+ * is accepted for an MBean <em>{@code name}</em> if {@link #getDynamicMBeanFor
+ * getDynamicMBeanFor}<code>(<em>name</em>)</code> returns an object that is a
+ * {@link NotificationEmitter}.  That is appropriate if
+ * {@code getDynamicMBeanFor}<code>(<em>name</em>)</code> always returns the
+ * same object for the same <em>{@code name}</em>.  But with
+ * Virtual MBeans, every call to {@code getDynamicMBeanFor} returns a new object,
+ * which is discarded as soon as the MBean request has finished.
+ * So a listener added to that object would be immediately forgotten.</p>
+ *
+ * <p>The simplest way for a subclass that defines Virtual MBeans
+ * to support notifications is to create a private {@link VirtualEventManager}
+ * and override the method {@link
+ * #getNotificationEmitterFor getNotificationEmitterFor} as follows:</p>
+ *
+ * <pre>
+ *     private final VirtualEventManager vem = new VirtualEventManager();
+ *
+ *     &#64;Override
+ *     public NotificationEmitter getNotificationEmitterFor(
+ *             ObjectName name) throws InstanceNotFoundException {
+ *         // Check that the name is a valid Virtual MBean.
+ *         // This is the easiest way to do that, but not always the
+ *         // most efficient:
+ *         getDynamicMBeanFor(name);
+ *
+ *         // Return an object that supports add/removeNotificationListener
+ *         // through the VirtualEventManager.
+ *         return vem.getNotificationEmitterFor(name);
+ *     }
+ * </pre>
+ *
+ * <p>A notification <em>{@code n}</em> can then be sent from the Virtual MBean
+ * called <em>{@code name}</em> by calling {@link VirtualEventManager#publish
+ * vem.publish}<code>(<em>name</em>, <em>n</em>)</code>.  See the example
+ * <a href="#virtual-notif-example">above</a>.</p>

+/**
+ *  <p>The <code>javax.management.namespace</code> package makes it possible
+ *  to federate MBeanServers into a hierarchical name space.</p>
+ *
+ *  <h3 id="WhatIs">What Is a Name Space?</h3>
+ *  <p>
+ *      A name space is like an {@link javax.management.MBeanServer} within
+ *      an {@code MBeanServer}. Just as a file system folder can contain
+ *      another file system folder, an {@code MBeanServer} can contain another
+ *      {@code MBeanServer}. Similarly, just as a remote folder on a remote
+ *      disk can be mounted on a parent folder on a local disk, a remote name
+ *      space in a remote {@code MBeanServer} can be mounted on a name
+ *      space in a local parent {@code MBeanServer}.
+ *  </p>
+ *  <p>
+ *      The <code>javax.management.namespace</code> API thus makes it possible to
+ *      create a hierarchy of MBean servers federated in a hierarchical name
+ *      space inside a single {@code MBeanServer}.
+ *  </p>
+ *  <h3 id="HowToCreate">How To Create a Name Space?</h3>
+ *  <p>
+ *      To create a name space, you only need to register a
+ *      {@link javax.management.namespace.JMXNamespace} MBean in
+ *      an MBean server. We have seen that a namespace is like
+ *      an {@code MBeanServer} within an {@code MBeanServer}, and
+ *      therefore, it is possible to create a namespace that shows the
+ *      content of another {@code MBeanServer}. The simplest case is
+ *      when that {@code MBeanServer} is another {@code MBeanServer}
+ *      created by the {@link javax.management.MBeanServerFactory} as
+ *      shown in the extract below:
+ *  </p>
+ *  <pre>
+ *  final MBeanServer server = ....;
+ *  final String namespace = "foo";
+ *  final ObjectName namespaceName = {@link javax.management.namespace.JMXNamespaces#getNamespaceObjectName
+ *        JMXNamespaces.getNamespaceObjectName(namespace)};
+ *  server.registerMBean(new JMXNamespace(MBeanServerFactory.newMBeanServer()),
+ *                      namespaceName);
+ *  </pre>
+ *  <p id="NamespaceView">
+ *     To navigate in namespaces and view their content, the easiest way is
+ *     to use an instance of {@link javax.management.namespace.JMXNamespaceView}. For instance, given
+ *     the {@code server} above, in which we created a namespace {@code "foo"},
+ *     it is possible to create a {@code JMXNamespaceView} that will make it
+ *     possible to navigate easily in the namespaces and sub-namespaces of that
+ *     server:
+ *  </p>
+ *  <pre>
+ *  // create a namespace view for 'server'
+ *  final JMXNamespaceView view = new JMXNamespaceView(server);
+ *
+ *  // list all top level namespaces in 'server'
+ *  System.out.println("List of namespaces: " + Arrays.toString({@link javax.management.namespace.JMXNamespaceView#list() view.list()}));
+ *
+ *  // go down into namespace 'foo': provides a namespace view of 'foo' and its
+ *  // sub namespaces...
+ *  final JMXNamespaceView foo = {@link javax.management.namespace.JMXNamespaceView#down view.down("foo")};
+ *
+ *  // list all MBeans contained in namespace 'foo'
+ *  System.out.println({@link javax.management.namespace.JMXNamespaceView#where() foo.where()} + " contains: " +
+ *         {@link javax.management.namespace.JMXNamespaceView#getMBeanServerConnection foo.getMBeanServerConnection()}.queryNames(null,null));
+ *  </pre>
+ * <p>
+ *   It is also possible to create more complex namespaces, such as namespaces
+ *   that point to MBean servers located in remote JVMs.
+ * </p>
+ * <p>
+ *      For instance, to mount the MBeanServer accessible
+ *      at <code>service:jmx:rmi:///jndi/rmi://localhost:9000/jmxrmi</code>
+ *      in a name space {@code "foo"} inside the {@linkplain
+ *      java.lang.management.ManagementFactory#getPlatformMBeanServer platform
+ *      MBeanServer} you would write the following piece of code:
+ *  </p>
+ *  <pre>
+ *      final JMXServiceURL sourceURL =
+ *         new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:9000/jmxrmi");
+ *      final MBeanServer platform = ManagementFactory.getPlatformMBeanServer();
+ *      final Map&lt;String,Object&gt; options = Collections.emptyMap();
+ *      final JMXRemoteNamespace mbean = {@link
+ *            javax.management.namespace.JMXRemoteNamespace JMXRemoteNamespace}.
+ *         {@link javax.management.namespace.JMXRemoteNamespace#newJMXRemoteNamespace newJMXRemoteNamespace(sourceURL, options)};
+ *      final ObjectName name = {@link javax.management.namespace.JMXNamespaces JMXNamespaces}.{@link javax.management.namespace.JMXNamespaces#getNamespaceObjectName(String) getNamespaceObjectName("foo")};
+ *      final ObjectInstance ref = platform.registerMBean(mbean,name);
+ *      platform.invoke(ref.getObjectName(),"connect",null,null);
+ *  </pre>
+ *
+ *  <h3 id="WhatLike">What Does a Name Space Look Like?</h3>
+ *
+ *  <p>
+ *   We have seen that {@link javax.management.namespace.JMXNamespaceView} class
+ *   provides an easy way to navigate within namespaces. It is however also
+ *   possible to interact with namespaces directly from the top level
+ *   {@code MBeanServer} in which they have been created.
+ *      From the outside, a name space only appears as a special MBean in
+ *      the MBean server. There's nothing much you can do with this MBean
+ *      directly.
+ *  </p>
+ *  <p>
+ *      For instance, let's assume you have registered a {@link
+ *      javax.management.namespace.JMXRemoteNamespaceMBean
+ *      JMXRemoteNamespaceMBean} to manage the name space {@code "foo"}.
+ *      <br>If you query for
+ *      <code>platform.queryNames("&#42;//:*",null)</code>, then you will see
+ *      one MBean named {@code "foo//:type=JMXNamespace"}.
+ *      <br>This is the {@link javax.management.namespace.JMXNamespace}
+ *      MBean which is in charge of handling the namespace {@code "foo"}.
+ *  </p>
+ *  <p>
+ *      In fact, name space handler MBeans are instances of
+ *      the class {@link javax.management.namespace.JMXNamespace} - or
+ *      instances of a subclass of that class.
+ *      They have a special {@link javax.management.ObjectName} defined by
+ *      {@link javax.management.namespace.JMXNamespaces#getNamespaceObjectName
+ *      JMXNamespaces.getNamespaceObjectName}.<br>
+ *      {@link javax.management.namespace.JMXNamespace} instances are able
+ *      to return an {@link
+ *      javax.management.namespace.JMXNamespace#getSourceServer MBeanServer}
+ *      which corresponds to the MBeanServer within (= the name space itself).
+ *  </p>
+ *  <p>
+ *      So how does it work? How can you see the MBeans contained in the new
+ *      name space?
+ *  </p>
+ *  <p>In order to address scalability issues, MBeans registered in
+ *     namespaces (such as our namespace {@code "foo"} above) can not be
+ *     seen with {@code mbeanServer.queryNames("*:*",null)}. To see the MBeans
+ *     contained in a namespace, you can use one of these methods:
+ *  </p>
+ *  <ol>
+ *      <li>
+ *          You can use the {@link javax.management.namespace.JMXNamespaceView}
+ *          class <a href="#NamespaceView">shown above</a>,
+ *      </li>
+ *      <li>
+ *          or you can <a href="#NamespacePrefix">directly look</a> for MBeans
+ *          whose names match
+ *         {@code "foo//*:*"},
+ *      </li>
+ *      <li>
+ *          or you can <a href="#ChangeTo">narrow down</a> to the namespace
+ *          and obtain an MBeanServer
+ *          proxy that corresponds to an MBeanServer view of that namespace.
+ *          The JMXNamespaces class provides a static method that
+ *          allows you to narrow down to a name space, by calling
+ *          {@link javax.management.namespace.JMXNamespaces#narrowToNamespace(MBeanServer,String)
+ *                 JMXNamespaces.narrowToNamespace}.
+ *      </li>
+ *  </ol>
+ *
+ *  <h3 id="NamespacePrefix">Using Name Space Prefixes</h3>
+ *  <p>
+ *      As we have explained above, MBeans contained in name
+ *      spaces are not returned by {@code server.queryNames(null,null)} - or
+ *      <code>server.queryNames({@link javax.management.ObjectName#WILDCARD ObjectName.WILDCARD},null)</code>.
+ *      <br>
+ *      However, these MBeans can still be accessed from the top level
+ *      {@code MBeanServer} interface, without using any API specific to the
+ *      version 2.0 of the JMX API, simply by using object names with
+ *      name space prefixes:
+ *      <br>To list MBeans contained in a namespace {@code "foo"} you can
+ *      query for MBeans whose names match {@code "foo//*:*"}, as shown
+ *      earlier in this document:
+ *      <pre>
+ *         server.queryNames(new ObjectName("foo//*:*", null);
+ *         // or equivalently:
+ *         server.queryNames(JMXNamespaces.getWildcardFor("foo"), null);
+ *      </pre>
+ *      This will return a list of MBean names whose domain name starts
+ *      with {@code foo//}.
+ *  </p><p>
+ *      Using these names, you can invoke any operation on the corresponding
+ *      MBeans. For instance, to get the {@link javax.management.MBeanInfo
+ *      MBeanInfo} of an MBean
+ *      contained in name space {@code "foo"} (assuming
+ *      the name of the MBean within its name space is <i>domain:type=Thing</i>,
+ *      then simply call:
+ *      <pre>
+ *         server.getMBeanInfo(new ObjectName("foo//domain:type=Thing"));
+ *      </pre>
+ *      An easier way to access MBeans contained in a name space is to
+ *      <i>cd</i> inside the name space, as shown in the following paragraph.
+ *  </p>
+ *
+ *  <h3 id="ChangeTo">Narrowing Down Into a Name Spaces</h3>
+ *  <p>
+ *      As we have seen, name spaces are like MBean servers within MBean servers.
+ *      Therefore, it is possible to view a name space just as if it were
+ *      an other MBean server. This is similar to opening a sub
+ *      folder from a parent folder.<br>
+ *      This operation is illustrated in the code extract below:
+ *      <pre>
+ *          final MBeanServer foo =
+ *                JMXNamespaces.narrowToNamespace(platform, "foo");
+ *          final MBeanInfo info =
+ *                foo.getMBeanInfo(new ObjectName("domain:type=Thing"));
+ *      </pre>
+ *      The {@code MBeanServer} returned by {@link
+ *      javax.management.namespace.JMXNamespaces#narrowToNamespace(MBeanServer,String)
+ *      JMXNamespaces.narrowToNamespace} is an {@code MBeanServer} view that
+ *      narrows down into a given namespace. The MBeans contained inside that
+ *      namespace can now be accessed by their regular local name. <br>
+ *      The MBean server obtained by narrowing down
+ *      to name space {@code "foo"} behaves just like a regular MBean server.
+ *      However, it may sometimes throw an {@link
+ *      java.lang.UnsupportedOperationException UnsupportedOperationException}
+ *      wrapped in a JMX exception if you try to call an operation which is not
+ *      supported by the underlying name space handler.
+ *      <br>For instance, {@link javax.management.MBeanServer#registerMBean
+ *      registerMBean} is not supported for name spaces mounted from remote
+ *      MBean servers.
+ *  </p>
+ *  <p>
+ *      <u>Note:</u> If you have a deep hierarchy of namespaces, and if you
+ *      are switching from one namespace to another in the course of your
+ *      application, it might be more convenient to use a
+ *      {@link javax.management.namespace.JMXNamespaceView}
+ *      in order to navigate in your namespaces.
+ *  </p>
+ *
+ *  <h3 id="NamespaceTypes">Different Types of Name Spaces</h3>
+ *      <p>
+ *          This API lets you create several types of name spaces:
+ *          <ul>
+ *              <li id="RemoteNS">
+ *                  You can use the {@link
+ *                  javax.management.namespace.JMXRemoteNamespace
+ *                  JMXRemoteNamespace} to create
+ *                  <b>remote</b> name spaces, mounted from
+ *                  a remote sub {@code MBeanServer} source, as shown
+ *                  <a href="#HowToCreate">earlier</a> in this document.
+ *              </li>
+ *              <li id="LocalNS">
+ *                  You can also use {@link

+ *      <p>
+ *          Just as folders can contain other folders, name spaces can contain
+ *          other name spaces. For instance, if an {@code MBeanServer} <i>S1</i>
+ *          containing a name space {@code "bar"} is mounted in another
+ *          {@code MBeanServer} <i>S2</i> with name space {@code "foo"}, then
+ *          an MBean <i>M1</i> named {@code "domain:type=Thing"} in namespace
+ *          {@code "bar"} will appear as {@code "foo//bar//domain:type=Thing"} in
+ *          {@code MBeanServer} <i>S2</i>.
+ *      </p>
+ *      <p>
+ *          When accessing the MBean <i>M1</i> from server <i>S2</i>, the
+ *          method call will traverse in a cascade {@code MBeanServer} <i>S2</i>,
+ *          then the name space handler for name space {@code "foo"}, then
+ *          {@code MBeanServer} <i>S1</i>, before coming to the name space
+ *          handler for name space {@code "bar"}.  Any operation invoked
+ *          on the MBean from a "top-level" name space will therefore need to
+ *          traverse all the name spaces along the name space path until
+ *          it eventually reaches the named MBean. This means that an operation
+ *          like <a href="#registerMBean">registerMBean</a> for instance,
+ *          can only succeed if all the name spaces along the path support it.
+ *      </p>
+ *      <p>
+ *          Narrowing to a nested name space works just the same as narrowing
+ *          to a top level name space:
+ *      <pre>
+ *          final MBeanServer S2 = .... ;
+ *          final MBeanServer bar =

+ *      </pre>
+ *      </p>
+ *
+ *      <h3 id="OperationResult">Name Spaces And Operation Results</h3>
+ *      <p>
+ *          Operation results, as well as attribute values returned by an MBean
+ *          contained in a name space must be interpreted in the context of that
+ *          name space.<br>
+ *          In other words, if an MBean in name space "foo" has an attribute of
+ *          type {@code ObjectName}, then it must be assumed that the
+ *          {@code ObjectName} returned by that MBean is relative to
+ *          name space "foo".<br>
+ *          The same rule aplies for MBean names that can be returned by
+ *          operations invoked on such an MBean. If one of the MBean operations
+ *          return, say, a {@code Set<ObjectName>} then those MBean names must
+ *          also be assumed to be relative to name space "foo".<br>
+ *      </p>
+ *      <p>
+ *          In the usual case, a JMX client will first
+ *          <a href="#ChangeTo">narrow to a name space</a> before invoking
+ *          any operation on the MBeans it contains. In that case the names
+ *          returned by the MBean invoked can be directly fed back to the
+ *          narrowed connection.
+ *          <br>
+ *          If however, the JMX client directly invoked the MBean from a higher
+ *          name space, without having narrowed to that name space first, then
+ *          the names that might be returned by that MBean will not be directly
+ *          usable - the JMX client will need to either
+ *          <a href="#ChangeTo">narrow to the name space</a> before using the
+ *          returned names, or convert the names to the higher level name space
+ *          context.
+ *          <br>
+ *          The {@link javax.management.namespace.JMXNamespaces JMXNamespaces}
+ *          class provides methods that can be used to perform that conversion.
+ *      </p>
+ *
+ *      <h3 id="NamespacesAndNotifications">Name Spaces And Notifications</h3>
+ *      <p>
+ *          As <a href="#WhatIs">already explained</a>, name spaces are very
+ *          similar to {@code MBeanServer}s. It is thus possible to get
+ *          {@link javax.management.MBeanServerNotification MBeanServerNotifications}
+ *          when MBeans are added or removed within a name space, by registering
+ *          with the {@link javax.management.MBeanServerDelegate
+ *          MBeanServerDelegate} MBean of the corresponding name space.<br>
+ *          However, it must be noted that the notifications emitted by a
+ *          name space must be interpreted in the context of that name space.
+ *          For instance, if an MBean {@code "domain:type=Thing"} contained in
+ *          namespace "foo//bar" emits a notification, the source of the
+ *          notification will be {@code "domain:type=Thing"}, not
+ *          {@code "foo//bar//domain:type=Thing"}. <br>
+ *          It is therefore recommended to keep track of the name space
+ *          information when registering a listener with an MBean contained in
+ *          a name space, especially if the same listener is used to receive
+ *          notifications from different name spaces. An easy solution is to
+ *          use the handback, as illustrated in the code below.
+ *          <pre>
+ *            final MBeanServer server = ...;
+ *            final NotificationListener listener = new NotificationListener() {

+ *                        System.err.println("Error: expected MBeanServerNotification");
+ *                        return;
+ *                    }
+ *                    final MBeanServerNotification mbsn =
+ *                            (MBeanServerNotification) n;
+ *
+ *                    // We will pass the namespace path in the handback.
+ *                    //
+ *                    // The received notification must be interpreted in

+ *                    // path...
+ *                    //
+ *                    final String namespace = (String) handback;

+ *      <p>
+ *          JMX Connectors may require some configuration in order to be able
+ *          to forward notifications from MBeans located in name spaces.
+ *          The RMI JMX Connector Server
+ *          in the Java SE 7 platform is configured by default to internally
+ *          use the new {@linkplain javax.management.event event service} on
+ *          the server side.
+ *          When the connector server is configured in this way, JMX clients
+ *          which use the old JMX Notifications mechanism (such as clients
+ *          running on prior versions of the JDK) will be able to
+ *          to receive notifications from MBeans located in sub name spaces.
+ *          This is because the connector server will transparently delegate
+ *          their subscriptions to the underlying {@linkplain
+ *          javax.management.event event service}. In summary:
+ *          <ul>
+ *              <li>
+ *                  On the server side: When exporting an {@code MBeanServer}
+ *                  through a JMX Connector, you will need to make sure that the
+ *                  connector server uses the new {@linkplain javax.management.event
+ *                  event service} in order to register for notifications. If the
+ *                  connector server doesn't use the event service, only clients
+ *                  which explicitly use the new {@linkplain javax.management.event
+ *                  event service} will be able to register for notifications
+ *                  with MBeans located in sub name spaces.
+ *              </li>
+ *              <li>
+ *                  On the client side: if the JMX Connector server (on the remote
+ *                  server side) was configured to internally use the new
+ *                  {@linkplain javax.management.event
+ *                  event service}, then clients can continue to use the old
+ *                  {@code MBeanServerConnection} add / remove notification
+ *                  listener methods transparently. Otherwise, only clients which
+ *                  explicitly use the new {@linkplain javax.management.event
+ *                  event service} will be able to receive notifications from
+ *                  MBeans contained in sub name spaces.
+ *              </li>
+ *          </ul>
+ *      </p>
+ *      <p>
+ *          These configuration issues apply at each node in the name space path,
+ *          whenever the name space points to a remote server. The
+ *          {@link javax.management.namespace.JMXRemoteNamespace
+ *          JMXRemoteNamespace} can be configured in such a way that it will
+ *          explicitly use an {@link javax.management.event.EventClient EventClient}
+ *          when forwarding subscription to the remote side. Note that this can be
+ *          unnecessary (and a waste of resources) if the underlying JMXConnector
+ *          returned by the JMXConnectorFactory (client side) already uses the
+ *          {@linkplain javax.management.event event service} to register for
+ *          notifications with the server side.

+ * @author Eamonn Mcmanus

+/**
+ * The idea is that we will create a hierarchy like this:
+ * a//
+ *   X
+ *   b//
+ *     Y
+ *     Z
+ * and we will use MXBean references so we have links like this:
+ * a//
+ *   X----+
+ *   b//  |
+ *       /
+ *     Y
+ *      \
+ *      /
+ *     Z
+ * In other words, X.getY() will return a proxy for Y, which the MXBean
+ * framework will map to b//Y.  A proxy for a//X should then map this
+ * into a proxy for a//b//Y.  That's easy.  But then if we call getZ()
+ * on this proxy, the MXBean framework will return just Z, and the proxy
+ * must map that into a proxy for a//b//Z.

+// MBeanServerSupport work correctly:
+// (1) as a special-purpose implementation of MBeanServer for a fixed number
+//     of MBeans (e.g. for QueryNotificationFilter)
+// (2) as an MBeanServer supporting Virtual MBeans.
+// In each case we are particularly interested in the notification behaviour.
+// We check that the behaviour is correct when calling addNotificationListener
+// (a) for an MBean that does not exist; (b) for an MBean that does exist but
+// is not a NotificationEmitter; and (c) for an MBean that exists and is
+// a NotificationEmitter.  We also check the degenerate and usual case
+// where the MBeanServerSupport subclass does not support notifications
+// at all.
+//
+// Each subclass will have an MBean called test:type=NotEmitter that
+// does not support addNotificationListener. If it also has MBeans called
+// test:type=Emitter,* then they are expected to support addNL. No subclass
+// will have any other MBeans, so in particular no subclass will have
+// test:type=Nonexistent.
