Comment 2 Tomas Hurka 2014-08-27 07:12:37 UTC 
There is a number of DiffSidebar instances held by one NBEditorDocument. See path to GCRoot for 
DiffSidebar#8
DiffSidebar#9
DiffSidebar#10
DiffSidebar#11
...
all are held by NBEditorDocument#7.
This problem is probably caused by cloning editor's topcomponent. Reassigning to editor for further evaluation.
Comment 3 Miloslav Metelka 2014-09-30 15:35:34 UTC 
I have went through all the stuff holding strong refs to QuietEditorPane instances after they get closed. Not only the cases when both QEP and its document get closed but also when an editor component gets cloned i.e. when the document instance remains due to an opened QEP and only a cloned QEP gets closed.
The QEP instances should now get GCed appropriately.

Log: #246698 - OutOfMemoryError: GC overhead limit exceeded - Ensure QuietEditorPane instances get GCed once they are closed including a case when only a cloned QEP gets closed.
