Created attachment 112950 [details] Reference chain Dev build. Had been working on various projects, then closed them all (all files closed too). Heap usage was still high, so took a dump and found a number of Project impls still in heap. One of the GC root references went through OpenedEditors. Not sure why the key (JTextComponent) was being held, but seems dangerous to hold the DataObject strongly.
Created attachment 112951 [details] Reference chain for another project, showing possible bug in AnnotationHolder; related?
Can confirm that the JavaDataObject shown was for a source file I had closed at least an hour before, in a project that had also been closed for some time.
Created attachment 112953 [details] Reference chain for a QuietEditorPane (one of 12 in heap) This chain suggests a problem due to having run a graphical diff on the file which was leaked.
Created attachment 112955 [details] Reference chain for yet another project
The problem in OpenedEditors might be that the event from closing the last editor did not arrive (the map contains at most one mapping), will check. The AnnotationHolder link is much more interesting, will need to check deeper (possibly the AH does not handle diff panes correctly?). The parsing.impl stuff is almost surely a consequence of the OpenedEditors (there are still tasks registered for the closed editor).

Integrated into 'main-golden' Changeset: http://hg.netbeans.org/main-golden/rev/4d254cf6d7f4 User: Jan Lahoda <jlahoda@netbeans.org> Log: #204798: a PropertyChangeEvent from a JTextComponent may arrive even after the component was removed from the EditorRegistry, need to prevent any work on that component in such a case.
