This annotation should be used on methods that need to be notified when the cache is used in a cluster and the
cluster topology experiences a merge event after a cluster split.
Methods annotated with this annotation should accept a single parameter, a
MergeEvent
otherwise a
IncorrectListenerException
will be thrown when registering your listener.
Any exceptions thrown by the listener will abort the call. Any other listeners not yet called will not be called,
and any transactions in progress will be rolled back.
