-/**
- * <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//**//*:type=JMXConnectorServer" when
- * // accessed from any MBeanServer whose name matches myapp.*"
- * permission javax.management.namespace.JMXNamespacePermission "myapp.*::stop[a//**//*: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>**//b//c//D:k=v</code> or <code>a//**//c//D:k=v</code>
- * - see ObjectName <a href="../ObjectName.html#metawildcard">documentation</a>
- * for more details.
- * </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>**//*:*</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//**//*:*]
- *
- * // allows access to Foo from all namespaces in the MBeanServer named
- * // 'myapp.srv1' - but not recursively.
- * myapp.srv1::Foo[*//*:*]
- * </pre>
- * <p>For instance, the first two permissions listed above
- * will let through {@code getAttribute("a//b//D:k=v","Foo");} in
- * all MBeanServers, but will block access to
- * {@code getAttribute("a//b//c//D:k=v","Foo");} in MBeanServers whose
- * name do not start with {@code "myapp."}.
- * </p>
- * <p><a name="metawildcard">Depending on how your namespace hierarchy
- * is defined some of these wildcard permission names can be useful</a>:</p>
- * <pre>
- * // allows access to Foo in all namespaces, recursively.
- * //
- * *::Foo[**//*:*]
- *
- * // This permission name is the equivalent to the permission names above:
- * // Foo[**//*:*] and Foo[] are equivalent.
- * //
- * Foo[]
- *
- * // This permission name is the equivalent to the two permission names
- * // above:
- * // Foo[**//*:*], Foo[], Foo are equivalent.
- * //
- * Foo
- *
- * // allows access to Foo from all namespaces - but not recursively.
- * // This wildcard permission complements the previous one: it allows
- * // access to 'Foo' from an MBean directly registered in any local namespace.
- * //
- * Foo[*//*:*]
- *
- * </pre>
- * <p><b>Note on wildcards:</b> In an object name pattern, a path element
- * of exactly <code>**</code> corresponds to a meta
- * wildcard that will match any number of sub namespaces.
- * See ObjectName <a href="../ObjectName.html#metawildcard">documentation</a>
- * for more details.</p>
- *
- * <p>If {@code <mbean server name>::} is omitted, then one of
- * <code>member</code> or <code>object name</code> may be omitted.
- * If the <code>object name</code> is omitted,
- * the <code>[]</code> may be too (but does not have to be). It is
- * not legal to omit all items, that is to have a <em>name</em>
- * which is the empty string.</p>
- * <p>If {@code <mbean server name>} is present, it <b>must be followed</b> by
- * the {@code "::"} separator - otherwise it will be interpreted as
- * a {@code member name}.
- * </p>
- *
- * <p>
- * One or more of the <a href="#MBeanServerName">MBean Server name</a>,
- * <a href="#Member">member</a>
- * or <a href="#MBeanName">object name</a> may be the character "<code>-</code>",
- * which is equivalent to a null value. A null value is implied by
- * any value (including another null value) but does not imply any
- * other value.
- * </p>
- *
