/**
* Management Bean for an HA-Service.
* Provides a convenient common base for cluster symmetric MBeans.
*
* This class is also a user transparent extension
* of the standard NotificationBroadcasterSupport
* to a clustered environment.
* Listeners register with their local broadcaster.
* Invoking sendNotification() on any broadcaster,
* will notify all listeners in the same cluster partition.
* TODO: The performance can be further optimized by avoiding broadcast messages
* when remote listener nodes are not interested (e.g. have no local subscribers)
* or by iterating locally over filters or remote listeners.
