+// The UseParallelOldGC collector is a stop-the-world garbage
+// collector that does parts of the collection using parallel threads.
+// The collection includes the tenured generation and the young
+// generation. The permanent generation is collected at the same
+// time as the other two generations but the permanent generation
+// is collect by a single GC thread. The permanent generation is
+// collected serially because of the requirement that during the
+// processing of a klass AAA, any objects reference by AAA must
+// already have been processed. This requirement is enforced by
+// a left (lower address) to right (higher address) sliding compaction.
+//
+// There are four phases of the collection.
+//
+// - marking phase
+// - summary phase
+// - compacting phase
+// - clean up phase
+//
+// Roughly speaking these phases correspond, respectively, to
+// - mark all the live objects
+// - calculate the destination of each object at the end of the collection
+// - move the objects to their destination
+// - update some references and reinitialize some variables
+//
+// These three phases are invoked in PSParallelCompact::invoke_no_policy().
+// The marking phase is implemented in PSParallelCompact::marking_phase()
+// and does a complete marking of the heap.
+// The summary phase is implemented in PSParallelCompact::summary_phase().
+// The move and update phase is implemented in PSParallelCompact::compact().
+//
+// A space that is being collected is divided into chunks and with
+// each chunk is associated an object of type ParallelCompactData.
+// Each chunk is of a fixed size and typically will contain more than
+// 1 object and may have parts of objects at the front and back of the
+// chunk.
+//
+// chunk -----+---------------------+----------
+// objects covered [ AAA )[ BBB )[ CCC )[ DDD )
+//
+// The marking phase does a complete marking of all live objects in the
+// heap. The marking also compiles the size of the data for
+// all live objects covered by the chunk. This size includes the
+// part of any live object spanning onto the chunk (part of AAA
+// if it is live) from the front, all live objects contained in the chunk
+// (BBB and/or CCC if they are live), and the part of any live objects
+// covered by the chunk that extends off the chunk (part of DDD if it is
+// live). The marking phase uses multiple GC threads and marking is
+// done in a bit array of type ParMarkBitMap. The marking of the
+// bit map is done atomically as is the accumulation of the size of the
+// live objects covered by a chunk.
+//
+// The summary phase calculates the total live data to the left of
+// each chunk XXX. Based on that total and the bottom of the space,
+// it can calculate the starting location of the live data in XXX.
+// The summary phase calculates for each chunk XXX quantites such as
+//
+// - the amount of live data at the beginning of a chunk from an object
+// entering the chunk.
+// - the location of the first live data on the chunk
+// - a count of the number of chunks receiving live data from XXX.
+//
+// See ParallelCompactData for precise details. The summary phase also
+// calculates the dense prefix for the compaction. The dense prefix
+// is a portion at the beginning of the space that is not moved. The
+// objects in the dense prefix do need to have their object references
+// updated. See method summarize_dense_prefix().
+//
+// The summary phase is done using 1 GC thread.
+//
+// The compaction phase moves objects to their new location and updates
+// all references in the object.
+//
+// A current exception is that objects that cross a chunk boundary
+// are moved but do not have their references updated. References are
+// not updated because it cannot easily be determined if the klass
+// pointer KKK for the object AAA has been updated. KKK likely resides
+// in a chunk to the left of the chunk containing AAA. These AAA's
+// have there references updated at the end in a clean up phase.
+// See the method PSParallelCompact::update_deferred_objects(). An
+// alternate strategy is being investigated for this deferral of updating.
+//
+// Compaction is done on a chunk basis. A chunk that is ready to be
+// filled is put on a ready list and GC threads take chunk off the list
+// and fill them. A chunk is ready to be filled if it
+// empty of live objects. Such a chunk may have been initially
+// empty (only contained
+// dead objects) or may have had all its live objects copied out already.
+// A chunk that compacts into itself is also ready for filling. The
+// ready list is initially filled with empty chunks and chunks compacting
+// into themselves. There is always at least 1 chunk that can be put on
+// the ready list. The chunks are atomically added and removed from
+// the ready list.

+// of a space.
+// The space in a generation is mangled when it is first
+// initialized and when the generation grows. The spaces
+// are not necessarily up-to-date when this mangling occurs
+// and the method mangle_region() is used.

+// need to be remangled. Remangling is only done on the
+// recently allocated regions in the space. Typically, that is
+// the region between the new top and the top just before a
+// garbage collection.
+// An exception to the usual mangling in a space is done when the
+// space is used for an extraordinary purpose. Specifically, when
+// to-space is used as scratch space for a mark-sweep-compact

+/**
+ * <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;
+ * }
+ *
+ * @Override
+ * protected {@code Set<ObjectName>} {@link #getNames getNames}() {
+ * return Collections.singleton(objectName);
+ * }
+ *
+ * @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);
+ * }
+ * }
+ *
+ * @Override
+ * public DynamicMBean {@link #getDynamicMBeanFor
+ * getDynamicMBeanFor}(ObjectName name)
+ * throws InstanceNotFoundException {
+ *
+ * // Check that the name is a legal one for a Property MBean
+ * ObjectName namePattern = newObjectName(
+ * "com.example:type=Property,name=\"*\"");
+ * if (!namePattern.apply(name))
+ * throw new InstanceNotFoundException(name);
+ *
+ * // Extract the name of the property that the MBean corresponds to
+ * 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);
+ * }
+ *
+ * @Override
+ * protected {@code Set<ObjectName>} {@link #getNames getNames}() {
+ * {@code Set<ObjectName> names = new TreeSet<ObjectName>();}
+ * 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>
+ *
+ * <pre>
+ * public class PropsMBS {
+ * ...as <a href="#PropsMBS">above</a>...
+ *
+ * private final {@link VirtualEventManager} vem = new VirtualEventManager();
+ *
+ * @Override
+ * public NotificationEmitter {@link #getNotificationEmitterFor
+ * getNotificationEmitterFor}(
+ * ObjectName name) throws InstanceNotFoundException {
+ * getDynamicMBeanFor(name); // check that the name is valid
+ * return vem.{@link VirtualEventManager#getNotificationEmitterFor
+ * getNotificationEmitterFor}(name);
+ * }
+ *
+ * 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,
+ * "Property " + name + " changed");
+ * n.setUserData(newValue);
+ * vem.{@link VirtualEventManager#publish publish}(objectName, n);
+ * }
+ * }
+ * </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();
+ *
+ * @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>A user can specify an {@link EventRelay} object to specify how to receive

+ * <p>A user can specify an {@link java.util.concurrent.Executor Executor}

+ * the notifications (in other words, to call the {@link
+ * NotificationListener#handleNotification handleNotification} method of the
+ * appropriate listeners). It is useful to make a separate thread do this
+ * distribution in some cases. For example, if network communication is slow,
+ * the forwarding thread can concentrate on communication while, locally,
+ * the distributing thread distributes the received notifications. Another
+ * usage is to share a thread pool between many clients, for scalability.
+ * Note, though, that if the {@code Executor} can create more than one thread
+ * then it is possible that listeners will see notifications in a different
+ * order from the order in which they were sent.</p>

+ * <p>This interface specifies necessary methods on the MBean server
+ * side for a JMX remote client to manage its notification listeners as
+ * if they are local.
+ * Users do not usually work directly with this MBean; instead, the {@link
+ * EventClient} class is designed to be used directly by the user.</p>
+ *
+ * <p>A default implementation of this interface can be added to an MBean
+ * Server in one of several ways.</p>
+ *
+ * <ul>
+ * <li><p>The most usual is to insert an {@link
+ * javax.management.remote.MBeanServerForwarder MBeanServerForwarder} between
+ * the {@linkplain javax.management.remote.JMXConnectorServer Connector Server}
+ * and the MBean Server, that will intercept accesses to the Event Client
+ * Delegate MBean and treat them as the real MBean would. This forwarder is
+ * inserted by default with the standard RMI Connector Server, and can also
+ * be created explicitly using {@link EventClientDelegate#newForwarder()}.
+ *
+ * <li><p>A variant on the above is to replace the MBean Server that is
+ * used locally with a forwarder as described above. Since
+ * {@code MBeanServerForwarder} extends {@code MBeanServer}, you can use
+ * a forwarder anywhere you would have used the original MBean Server. The
+ * code to do this replacement typically looks something like this:</p>
+ *
+ * <pre>
+ * MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); // or whatever
+ * MBeanServerForwarder mbsf = EventClientDelegate.newForwarder();
+ * mbsf.setMBeanServer(mbs);
+ * mbs = mbsf;
+ * // now use mbs just as you did before, but it will have an EventClientDelegate
+ * </pre>
+ *
+ * <li><p>The final way is to create an instance of {@link EventClientDelegate}
+ * and register it in the MBean Server under the standard {@linkplain
+ * #OBJECT_NAME name}:</p>
+ *
+ * <pre>
+ * MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); // or whatever
+ * EventClientDelegate ecd = EventClientDelegate.getEventClientDelegate(mbs);
+ * mbs.registerMBean(ecd, EventClientDelegateMBean.OBJECT_NAME);
+ * <pre>
+ * </ul>
+ *
+ * @since JMX 2.0

+/**
+ * <p>Defines the <em>Event Service</em>, which provides extended support
+ * for JMX notifications.</p>
+ *
+ * <p>The Event Service provides greater control over
+ * notification handling than the default technique using {@link
+ * javax.management.MBeanServer#addNotificationListener(ObjectName,
+ * NotificationListener, NotificationFilter, Object)
+ * MBeanServer.addNotificationListener} or {@link
+ * javax.management.MBeanServerConnection#addNotificationListener(ObjectName,
+ * NotificationListener, NotificationFilter, Object)
+ * MBeanServerConnection.addNotificationListener}.</p>
+ *
+ * <p>Here are some reasons you may want to use the Event Service:</p>
+ *
+ * <ul>
+ * <li>To receive notifications from a set of MBeans defined by an
+ * ObjectName pattern, such as {@code com.example.config:type=Cache,*}.
+ *
+ * <li>When the notification-handling behavior of the connector you are
+ * using does not match your requirements. For example, with the standard
+ * RMI connector you can lose notifications if there are very many of them
+ * in the MBean Server you are connected to, even if you are only listening
+ * for a small proportion of them.
+ *
+ * <li>To change the threading behavior of notification dispatch.
+ *
+ * <li>To define a different transport for notifications, for example to
+ * arrange for them to be delivered through the Java Message Service (<a
+ * href="http://java.sun.com/jms">JMS</a>). The Event Service comes with
+ * one alternative transport as standard, a "push-mode" RMI transport.
+ *
+ * <li>To handle notifications on behalf of MBeans (often virtual) in a
+ * namespace.
+ * </ul>
+ *
+ * <p>The Event Service is new in version 2.0 of the JMX API, which is the
+ * version introduced in version 7 of the Java SE platform. It is not usually
+ * possible to use the Event Service when connecting remotely to an
+ * MBean Server that is running an earlier version.</p>
+ *
+ *
+ * <h3 id="handlingremote">Handling remote notifications with the Event
+ * Service</h3>
+ *
+ * <p>Prior to version 2.0 of the JMX API, every connector
+ * had to include logic to handle notifications. The standard {@linkplain
+ * javax.management.remote.rmi RMI} and JMXMP connectors defined by <a
+ * href="http://jcp.org/en/jsr/detail?id=160">JSR 160</a> handle notifications
+ * in a way that is not always appropriate for applications. Specifically,
+ * the connector server adds one listener to every MBean that might emit
+ * notifications, and adds all received notifications to a fixed-size
+ * buffer. This means that if there are very many notifications, a
+ * remote client may miss some, even if it is only registered for a
+ * very small subset of notifications. Furthermore, since every {@link
+ * javax.management.NotificationBroadcaster NotificationBroadcaster} MBean
+ * gets a listener from the connector server, MBeans cannot usefully optimize
+ * by only sending notifications when there is a listener. Finally, since
+ * the connector server uses just one listener per MBean, MBeans cannot
+ * impose custom behavior per listener, such as security checks or localized
+ * notifications.</p>
+ *
+ * <p>The Event Service does not have these restrictions. The RMI connector
+ * that is included in this version of the JMX API uses the Event Service by
+ * default, although it can be configured to have the previous behavior if
+ * required.</p>
+ *
+ * <p>The Event Service can be used with <em>any</em> connector via the
+ * method {@link javax.management.event.EventClient#getEventClientConnection
+ * EventClient.getEventClientConnection}, like this:</p>
+ *
+ * <pre>
+ * JMXConnector conn = ...;
+ * MBeanServerConnection mbsc = conn.getMBeanServerConnection();
+ * MBeanServerConnection eventMbsc = EventClient.getEventClientConnection(mbsc);
+ * </pre>
+ *
+ * <p>If you add listeners using {@code eventMbsc.addNotificationListener}
+ * instead of {@code mbsc.addNotificationListener}, then they will be handled
+ * by the Event Service rather than by the connector's notification system.</p>
+ *
+ * <p>For the Event Service to work, either the {@link
+ * javax.management.event.EventClientDelegateMBean EventClientDelegateMBean}
+ * must be registered in the MBean Server, or the connector server must
+ * be configured to simulate the existence of this MBean, for example
+ * using {@link javax.management.event.EventClientDelegate#newForwarder()
+ * EventClientDelegate.newForwarder()}. The standard RMI connector is so
+ * configured by default. The {@code EventClientDelegateMBean} documentation
+ * has further details.</p>
+ *
+ *
+ * <h3 id="subscribepattern">Receiving notifications from a set of MBeans</h3>
+ *
+ * <p>The Event Server allows you to receive notifications from every MBean
+ * that matches an {@link javax.management.ObjectName ObjectName} pattern.
+ * For local clients (in the same JVM as the MBean Server), the {@link
+ * javax.management.event.EventSubscriber EventSubscriber} class can be used for
+ * this. For remote clients, or if the same code is to be used locally and
+ * remotely, use an
+ * {@link javax.management.event.EventClient EventClient}.</p>
+ *
+ * <p>EventSubscriber and EventClient correctly handle the case where a new
+ * MBean is registered under a name that matches the pattern. Notifications
+ * from the new MBean will also be received.</p>
+ *
+ * <p>Here is how to receive notifications from all MBeans in a local
+ * {@code MBeanServer} that match {@code com.example.config:type=Cache,*}:</p>
+ *
+ * <pre>
+ * MBeanServer mbs = ...;
+ * NotificationListener listener = ...;
+ * ObjectName pattern = new ObjectName("com.example.config:type=Cache,*");
+ * EventSubscriber esub = EventSubscriber.getEventSubscriber(mbs);
+ * esub.{@link javax.management.event.EventSubscriber#subscribe
+ * subscribe}(pattern, listener, null, null);
+ * </pre>
+ *
+ * <p>Here is how to do the same thing remotely:</p>
+ *
+ * <pre>
+ * MBeanServerConnection mbsc = jmxConnector.getMBeanServerConnection();
+ * EventClient events = new EventClient(mbsc);
+ * NotificationListener listener = ...;
+ * ObjectName pattern = new ObjectName("com.example.config:type=Cache,*");
+ * events.{@link javax.management.event.EventClient#subscribe
+ * subscribe}(pattern, listener, null, null);
+ * </pre>
+ *
+ *
+ * <h3 id="threading">Controlling threading behavior for notification
+ * dispatch</h3>
+ *
+ * <p>The EventClient class can be used to control threading of listener
+ * dispatch. For example, to arrange for all listeners to be invoked
+ * in the same thread, you can create an {@code EventClient} like this:</p>
+ *
+ * <pre>
+ * MBeanServerConnection mbsc = ...;
+ * Executor singleThreadExecutor = {@link
+ * java.util.concurrent.Executors#newSingleThreadExecutor()
+ * Executors.newSingleThreadExecutor}();
+ * EventClient events = new EventClient(
+ * mbsc, null, singleThreadExecutor, EventClient.DEFAULT_LEASE_TIMEOUT);
+ * events.addNotificationListener(...);
+ * events.subscribe(...);
+ * </pre>
+ *
+ *
+ * <h3 id="leasing">Leasing</h3>
+ *
+ * <p>The {@code EventClient} uses a <em>lease</em> mechanism to ensure
+ * that resources are eventually released on the server even if the client
+ * does not explicitly clean up. (This can happen through network
+ * partitioning, for example.)</p>
+ *
+ * <p>When an {@code EventClient} registers with the {@code
+ * EventClientDelegateMBean} using one of the {@code addClient} methods,
+ * an initial lease is created with a default expiry time. The {@code
+ * EventClient} requests an explicit lease shortly after that, with a
+ * configurable expiry time. Then the {@code EventClient} periodically
+ * <em>renews</em> the lease before it expires, typically about half way
+ * through the lifetime of the lease. If at any point the lease reaches
+ * the expiry time of the last renewal then it expires, and {@code
+ * EventClient} is unregistered as if it had called the {@link
+ * javax.management.event.EventClientDelegateMBean#removeClient removeClient}
+ * method.</p>
+ *
+ *
+ * <h3 id="transports">Custom notification transports</h3>
+ *
+ * <p>When you create an {@code EventClient}, you can define the transport
+ * that it uses to deliver notifications. The transport might use the
+ * Java Message Service (<a href="http://java.sun.com/jms">JMS</a>) or
+ * any other communication system. Specifying a transport is useful for
+ * example when you want different network behavior from the default, or
+ * different reliability guarantees. The default transport calls {@link
+ * javax.management.event.EventClientDelegateMBean#fetchNotifications
+ * EventClientDelegateMBean.fetchNotifications} repeatedly, which usually means
+ * that there must be a network connection permanently open between the client
+ * and the server. If the same client is connected to many servers this can
+ * cause scalability problems. If notifications are relatively rare, then
+ * JMS or the {@linkplain javax.management.event.RMIPushEventRelay push-mode
+ * RMI transport} may be more suitable.</p>
+ *
+ * <p>A transport is implemented by an {@link javax.management.event.EventRelay
+ * EventRelay} on the client side and a corresponding {@link
+ * javax.management.event.EventForwarder EventForwarder}
+ * on the server side. An example is the {@link
+ * javax.management.event.RMIPushEventRelay RMIPushEventRelay} and its
+ * {@link javax.management.event.RMIPushEventForwarder RMIPushEventForwarder}.</p>
+ *
+ * <p>To use a given transport with an {@code EventClient}, you first create
+ * an instance of its {@code EventRelay}. Typically the {@code EventRelay}'s
+ * constructor will have a parameter of type {@code MBeanServerConnection}
+ * or {@code EventClientDelegateMBean}, so that it can communicate with the
+ * {@code EventClientDelegateMBean} in the server. For example, the {@link
+ * javax.management.event.RMIPushEventForwarder RMIPushEventForwarder}'s constructors
+ * all take an {@code EventClientDelegateMBean} parameter, which is expected to
+ * be a {@linkplain javax.management.JMX#newMBeanProxy(MBeanServerConnection,
+ * ObjectName, Class) proxy} for the {@code EventClientDelegateMBean} in the
+ * server.</p>
+ *
+ * <p>When it is created, the {@code EventRelay} will call
+ * {@link javax.management.event.EventClientDelegateMBean#addClient(String,
+ * Object[], String[]) EventClientDelegateMBean.addClient}. It passes the
+ * name of the {@code EventForwarder} class and its constructor parameters.
+ * The {@code EventClientDelegateMBean} will instantiate this class using
+ * {@link javax.management.MBeanServer#instantiate(String, Object[], String[])
+ * MBeanServer.instantiate}, and it will return a unique <em>client id</em>.</p>
+ *
+ * <p>Then you pass the newly-created {@code EventRelay} to one of the {@code
+ * EventClient} constructors, and you have an {@code EventClient} that uses the
+ * chosen transport.</p>
+ *
+ * <p>For example, when you create an {@code RMIPushEventRelay}, it
+ * uses {@code MBeanServerDelegateMBean.addClient} to create an {@code
+ * RMIEventForwarder} in the server. Notifications will then be delivered
+ * through an RMI communication from the {@code RMIEventForwarder} to the
+ * {@code RMIPushEventRelay}.</p>
+ *
+ *
+ * <h4 id="writingcustomtransport">Writing a custom transport</h4>
+ *
+ * <p>To write a custom transport, you need to understand the sequence
+ * of events when an {@code EventRelay} and its corresponding {@code
+ * EventForwarder} are created, and when a notification is sent from the {@code
+ * EventForwarder} to the {@code EventRelay}.</p>
+ *
+ * <p>When an {@code EventRelay} is created:</p>
+ *
+ * <ul>
+ * <li><p>The {@code EventRelay} must call {@code
+ * EventClientDelegateMBean.addClient} with the name of the {@code
+ * EventForwarder} and the constructor parameters.</p>
+ *
+ * <li><p>{@code EventClientDelegateMBean.addClient} will do the following
+ * steps:</p>
+ *
+ * <ul>
+ * <li>create the {@code EventForwarder} using {@code MBeanServer.instantiate};
+ * <li>allocate a unique client id;
+ * <li>call the new {@code EventForwarder}'s {@link
+ * javax.management.event.EventForwarder#setClientId setClientId} method with
+ * the new client id;
+ * <li>return the client id to the caller.
+ * </ul>
+ *
+ * </ul>
+ *
+ * <p>When an {@code EventClient} is created with an {@code EventRelay}
+ * parameter, it calls {@link javax.management.event.EventRelay#setEventReceiver
+ * EventRelay.setEventReceiver} with an {@code EventReceiver} that the
+ * {@code EventRelay} will use to deliver notifications.</p>
+ *
+ * <p>When a listener is added using the {@code EventClient}, the
+ * {@code EventRelay} and {@code EventForwarder} are not involved.</p>
+ *
+ * <p>When an MBean emits a notification and a listener has been added
+ * to that MBean using the {@code EventClient}:</p>
+ *
+ * <ul>
+ * <li><p>The {@code EventForwarder}'s
+ * {@link javax.management.event.EventForwarder#forward forward} method
+ * is called with the notification and a <em>listener id</em>.</p>
+ *
+ * <li><p>The {@code EventForwarder} sends the notification and listener id
+ * to the {@code EventRelay} using the custom transport.</p>
+ *
+ * <li><p>The {@code EventRelay} delivers the notification by calling
+ * {@link javax.management.event.EventReceiver#receive EventReceiver.receive}.</p>
+ * </ul>
+ *
+ * <p>When the {@code EventClient} is closed ({@link
+ * javax.management.event.EventClient#close EventClient.close}):</p>
+ *
+ * <ul>
+ * <li><p>The {@code EventClient} calls {@link
+ * javax.management.event.EventRelay#stop EventRelay.stop}.</p>
+ *
+ * <li><p>The {@code EventClient} calls {@link
+ * javax.management.event.EventClientDelegateMBean#removeClient
+ * EventClientDelegateMBean.removeClient}.</p>
+ *
+ * <li><p>The {@code EventClientDelegateMBean} removes any listeners it
+ * had added on behalf of this {@code EventClient}.</p>
+ *
+ * <li><p>The {@code EventClientDelegateMBean} calls
+ * {@link javax.management.event.EventForwarder#close EventForwarder.close}.</p>
+ * </ul>
+ *
+ *
+ * <h4 id="threading">Threading and buffering</h3>
+ *
+ * <p>The {@link javax.management.event.EventForwarder#forward
+ * EventForwarder.forward} method may be called in the thread that the
+ * source MBean is using to send its notification. MBeans can expect
+ * that notification sending does not block. Therefore a {@code forward}
+ * method will typically add the notification to a queue, with a separate
+ * thread that takes notifications off the queue and sends them.</p>
+ *
+ * <p>An {@code EventRelay} does not usually need to buffer notifications
+ * before giving them to
+ * {@link javax.management.event.EventReceiver#receive EventReceiver.receive}.
+ * Although by default each such notification will be sent to potentially-slow
+ * listeners, if this is a problem then an {@code Executor} can be given to
+ * the {@code EventClient} constructor to cause the listeners to be called
+ * in a different thread.</p>
+ *

+ * chain.</p>

+ *
+ * Initially, the chain can be empty if this JMXConnectorServer was

+ * and userMBS will be null. If there is initially an MBeanServer,
+ * then both systemMBS and userMBS will point to it.
+ *
+ * Whenever userMBS is changed, the system chain must be updated. If there
+ * are forwarders in the system chain (between systemMBS and userMBS in the
+ * picture above), then the last one must point to the old value of userMBS
+ * (possibly null). It must be updated to point to the new value. If there
+ * are no forwarders in the system chain, then systemMBS must be updated to
+ * the new value of userMBS. The invariant is that starting from systemMBS
+ * and repeatedly calling MBSF.getMBeanServer() you will end up at
+ * userMBS. The implication is that you will not see any MBeanServer
+ * object on the way that is not also an MBeanServerForwarder.
+ *
+ * The method insertUserMBeanServer contains the logic to change userMBS
+ * and adjust the system chain appropriately.
+ *
+ * If userMBS is null and this JMXConnectorServer is registered in an
+ * MBeanServer, then userMBS becomes that MBeanServer, and the system
+ * chain must be updated as just described.
+ *
+ * When systemMBS is updated, there is no effect on userMBS. The system
+ * chain may contain forwarders even though the user chain is empty
+ * (there is no MBeanServer). In that case an attempt to forward an
+ * incoming request through the chain will fall off the end and fail with a
+ * NullPointerException. Usually a connector server will refuse to start()

+ * by X's ObjectName. To do this, we wrap the user's listener in
+ * a RewriteListener. But if the same listener is added a second
+ * time (perhaps with a different filter or handback) we must
+ * reuse the same RewriteListener so that the two-argument
+ * removeNotificationListener(ObjectName,NotificationListener) will
+ * correctly remove both listeners. This means we must remember the
+ * mapping from listener to WrappedListener. But if the MBean
+ * discards its listeners (as a result of removeNL or spontaneously)
+ * then we don't want to keep a reference to the WrappedListener.
+ * So we have tons of WeakReferences. The key in the ListenerTable
+ * is an IdentityListener, which wraps the user's listener to ensure
+ * that identity and not equality is used during the lookup, even if
+ * the user's listener has an equals method. The value in the
+ * ListenerTable is a WeakReference wrapping a RewriteListener wrapping
+ * the same IdentityListener. Since the RewriteListener is what is
+ * added to the user's MBean, the WeakReference won't disappear as long
+ * as the MBean still has this listener. And since it references the
+ * IdentityListener, that won't disappear either. But once the
+ * RewriteListener is no longer referenced by the user's MBean,
+ * there's nothing to stop its WeakReference from being cleared,
+ * and then corresponding IdentityListener that is now only weakly

+/*
+ * This test checks that it is possible to use the Event Service to create
+ * a "reconnectable connector".
+ *
+ * In the JMX Remote API, we deliberately specified that a connector client
+ * (JMXConnector) that encounters a network failure is then permanently broken.
+ * The idea being that adding recovery logic to the basic connector client
+ * would make it much more complicated and less reliable, and the logic would
+ * in any case never correspond to what a given situation needs. Some of
+ * the tough questions are: Should the connector try to mask the failure by
+ * blocking operations until the failure is resolved? How long should the
+ * connector try to reestablish the connection before giving up? Rather than
+ * try to solve this problem in the connector, we suggested that people who
+ * wanted to recover from network failures could implement the JMXConnector
+ * interface themselves so that it forwards to a wrapped JMXConnector that can
+ * be replaced in case of network failure.
+ *
+ * This works fine except that the connector client has state,
+ * in the form of listeners added by the user through the
+ * MBeanServerConnection.addNotificationListener method. It's possible
+ * for the wrapper to keep track of these listeners as well as forwarding
+ * them to the wrapped JMXConnector, so that it can reapply them to
+ * a replacement JMXConnector after failure recover. But it's quite
+ * tricky, particularly because of the two- and four-argument versions of
+ * removeNotificationListener.
+ *
+ * The Event Service can take care of this for you through the EventClient
+ * class. Listeners added through that class are implemented in a way that
+ * doesn't require the connector client to maintain any state, so they should
+ * continue to work transparently after replacing the wrapped JMXConnector.
+ * This test is a proof of concept that shows it works. Quite a number of
+ * details would need to be changed to build a reliable reconnectable
+ * connector.
+ *
+ * The test simulates network failure by rewrapping the wrapped JMXConnector's
+ * MBeanServerConnection (MBSC) in a "breakable" MBSC which we can cause
+ * to stop working. We do this in two phases. The first phase suspends
+ * any MBSC calls just at the point where they would return to the caller.
+ * The goal here is to block an EventClientDelegateMBean.fetchNotifications
+ * operation when it has received notifications but not yet delivered them
+ * to the EventClient. This is the most delicate point where a breakage
+ * can occur, because the EventClientDelegate must not drop those notifs
+ * from its buffer until another fetchNotifs call arrives with a later
+ * sequence number (which is an implicit ack of the previous set of
+ * notifs). Once the fetchNotifs call is suspended, we "kill" the MBSC,
+ * causing it to throw IOException from this and any other calls. That
+ * triggers the reconnect logic, which will make a new MBSC and issue
+ * the same fetchNotifs call to it.
+ *
+ * The test could be improved by synchronizing explicitly between the
+ * breakable MBSC and the mainline, so we only proceed to kill the MBSC
+ * when we are sure that the fetchNotifs call is blocked. As it is,
+ * we have a small delay which both ensures that no notifs are delivered
+ * while the connection is suspended, and if the machine is fast enough
+ * allows the fetchNotifs call to reach the blocking point.
