Currently the listeners are held in an ArrayList which is iterated over when an
event is fired. If you have two registered listeners, and in the handling of the
event in listener one you perform 'glDrawable.removeGLEventListener(this)', the
second listener will not receive the event.
There is a nice solution to this problem in the java.awt.AWTEventMulticaster
class. It would be nice if jogl used a similar approach.

Fixed by cloning the listeners list in the GLDrawableHelper upon add/remove.
