> ProxyFactoryHA registers a JMX notification listener for the shutdown of its target service and removes the proxy from JNDI on receipt of the notification.  HAServiceMBeanSupport broadcasts its JMX notifications *across the cluster*.  The effect of this is that the ProxyFactoryHA on all cluster nodes will receive the notification when any one instance of the service undeploys.  The effect is all proxies across the cluster are removed from JNDI.
> Test org.jboss.test.cluster.jmx.test.HAInvokerUnitTestCase demonstrates this.
> Following is a deliberately created stacktrace showing the origin of a notification that caused an invalid removal from JNDI:
