<Swing Dev> [PATCH] 7168064: SwingUtilities.sharedOwnerFrame multiplies window close event

[Jose Luis Martin]

Hello, 

I reported this issue one year ago but seems that it has been removed
from the public bug database and is still not fixed so I try now to
speak directly with you to see if this really is a bug or not.

The problem that I see is that a child window already disposed is
re-disposed when the owner frame is disposed, multiplying the
WINDOW_CLOSED events.

I guess that it could be fixed by testing if the child window is
displayable before disposing it in the Window dispose action. (May be
better in the dispose method itself).

I attach patch over last jdk8 repository and a test case for the issue.

Thanks, 

Best Regards.
