Kindly review the changes made for below bug
Problem description and solution are explained in comments section
https://bugs.openjdk.java.net/browse/JDK-6515161
diff for*ClientNotifForwarder.java *might be a bit confusing as it shows
the method name
removeNotificationListener is modified to getListenerIds and new method
removeNotificationListener is introduced.
Actual change is new method getListenerIds is introduced and it is
called in removeNotificationListener method without
affecting the functionality of removeNotificationListener.
