Example 33 with RuntimeOperationsException

use of javax.management.RuntimeOperationsException in project jdk8u_jdk by JetBrains.

the class DefaultMBeanServerInterceptor method addNotificationListener.

/*
     * Notification handling.
     *
     * This is not trivial, because the MBeanServer translates the
     * source of a received notification from a reference to an MBean
     * into the ObjectName of that MBean.  While that does make
     * notification sending easier for MBean writers, it comes at a
     * considerable cost.  We need to replace the source of a
     * notification, which is basically wrong if there are also
     * listeners registered directly with the MBean (without going
     * through the MBean server).  We also need to wrap the listener
     * supplied by the client of the MBeanServer with a listener that
     * performs the substitution before forwarding.  This is why we
     * strongly discourage people from putting MBean references in the
     * source of their notifications.  Instead they should arrange to
     * put the ObjectName there themselves.
     *
     * However, existing code relies on the substitution, so we are
     * stuck with it.
     *
     * Here's how we handle it.  When you add a listener, we make a
     * ListenerWrapper around it.  We look that up in the
     * listenerWrappers map, and if there was already a wrapper for
     * that listener with the given ObjectName, we reuse it.  This map
     * is a WeakHashMap, so a listener that is no longer registered
     * with any MBean can be garbage collected.
     *
     * We cannot use simpler solutions such as always creating a new
     * wrapper or always registering the same listener with the MBean
     * and using the handback to find the client's original listener.
     * The reason is that we need to support the removeListener
     * variant that removes all (listener,filter,handback) triples on
     * a broadcaster that have a given listener.  And we do not have
     * any way to inspect a broadcaster's internal list of triples.
     * So the same client listener must always map to the same
     * listener registered with the broadcaster.
     *
     * Another possible solution would be to map from ObjectName to
     * list of listener wrappers (or IdentityHashMap of listener
     * wrappers), making this list the first time a listener is added
     * on a given MBean, and removing it when the MBean is removed.
     * This is probably more costly in memory, but could be useful if
     * some day we don't want to rely on weak references.
