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 If the obj is a WeldMethodExpression, it returns false which cause add duplicated Listener listener in Mojarra 2.1

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

    }
{code}
