This memory leak prevents a closed java project from being garbage collected.

Comment 1 Jan Becicka 2007-12-14 17:52:26 UTC
I don't think, that problem is in cell renderer. It holds what it is required to render. Question is who holds the
CopyClassPanel? I assume that all refactoring windows are closed and CopyClassPanel should be released...
Comment 2 Jaroslav Tulach 2007-12-14 20:35:34 UTC
CopyClassPanel has static field that holds on the rest...

OK. You are right.
