Description:

The equals() implementation is incorrect

{code}
@Override
public boolean equals(Object obj) {
//my fix
     if (obj !=null && obj instanceof ForwardingMethodExpression){
     obj=((ForwardingMethodExpression)obj).delegate();
     }
//my fix end
     return this == obj || delegate().equals(obj);
}
{code}
If the obj is a WeldMethodExpression, it returns false which cause add duplicated listener in Mojarra 2.1

Please see Mojarra  javax.faces. componentUIComponentBase component.UIComponentBase
{code}
public void subscribeToEvent(Class<? extends SystemEvent> eventClass,
       ComponentSystemEventListener componentListener) {
...
    if (!listenersForEventClass.contains(facesLifecycleListener)) { // see here
        listenersForEventClass.add(facesLifecycleListener);
    }

}
{code}
