Description

A duplicate registration is when the exact same instance is registered twice:

MyListener listener = new MyListener();
muleContext.registerListener(listener);
muleContext.registerListener(listener);

This should result in listener being invoked once and not twice as it is currently, for the notification it is listening to.
