-------------------------------------
    Description: 
For a while we've seen rare failures of JMX tests that look like this:

{code}
java.lang.RuntimeException: java.security.PrivilegedActionException: javax.management.ListenerNotFoundException: Unknown listener
    at org.jboss.as.jmx.rbac.JmxRbacTestCase.checkMBeanAccess(JmxRbacTestCase.java:484)
    at org.jboss.as.jmx.rbac.JmxRbacTestCase.testMonitorNonSensitiveMBeans(JmxRbacTestCase.java:219)

    at org.jboss.as.jmx.rbac.JmxRbacTestCase.testMonitorNonSensitiveMBeans(JmxRbacTestCase.java:219)
   ...

    at org.jboss.as.jmx.PluggableMBeanServerImpl$TcclMBeanServer.removeNotificationListener(PluggableMBeanServerImpl.java:1544)
    at org.jboss.as.jmx.PluggableMBeanServerImpl.removeNotificationListener(PluggableMBeanServerImpl.java:969)
    at org.jboss.as.jmx.rbac.JmxRbacTestCase$1.run(JmxRbacTestCase.java:368)
    at org.jboss.as.jmx.rbac.JmxRbacTestCase$1.run(JmxRbacTestCase.java:254)
    at java.security.AccessController.doPrivileged(Native Method)
    at javax.security.auth.Subject.doAs(Subject.java:422)
    at org.jboss.as.jmx.rbac.JmxRbacTestCase.checkMBeanAccess(JmxRbacTestCase.java:254)
    at org.jboss.as.jmx.rbac.JmxRbacTestCase.testMonitorNonSensitiveMBeans(JmxRbacTestCase.java:219)
{code}

The problem is the TestModelMBean used by the test is not holding a ref to the "listenerWrapper" that the JVM MBeanServer passes into its addNotificationListener method. That allows that listenerWrapper to be gc'd, resulting in the failure of the removeNotificationListener call on the next line of the test.

The test holding a ref to the listener doesn't matter, as it's a "listenerWrapper" object that matters.
