Description

Steps to reproduce:
1. create a class that extends UIComponent
2. new an instances of that class
3.

Actual Results: The new instance is always in memory, even after needed, because of lines
1078 addEventListener(Event.ADDED, addedHandler);
1079 addEventListener(Event.REMOVED, removedHandler);
of UIComponent's constructor found in file UIComponent.as
which add a reference of the new instance to the flash side.

Expected Results: Some way to free up that instance. Either the class should have a way to call removeEventListener or the derived class should have access to the addedHandler and removedHandler so that it can call removeEventListner, and thus have the garbage collector delete the instance.

Workaround (if any):
