On the other hand, I have found a threading bug in AWT GLCanvas
in case other threads injected 'display()' (animator) before
issuing removeNotify(). In that case, the display() is still
processed 'later on' after disposal.
Thanx to your test case, which triggers this situation occasionally.
After fix I will retest w/ jdk6.
