<AWT Dev> [8] Review request for CR 7079254 Toolkit eventListener leaks memory

[Petr Pchelko]

Hello.

Could you please review the fix for the issue
7079254 Toolkit eventListener leaks memory
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7079254

The webrev is available at:

The LightweightDispatcher stored strong references to mouseEventTarget and targetLastEntered which were not cleaned up when the component is removed, which lead to a memory leak. The isCleaned field is added to be able to consume events which would be dispatched to a removed component if we did not clean up a reference to it. 

The fix testet on Windows and Mac on toy apps and automatic regression tests related to event dispatching, Component, Container, dnd and Mouse

Best, Petr.
