Description Marek Fukala 2014-07-25 08:01:39 UTC

Please take a look at the following heap dump

http://statistics.netbeans.org/exceptions/exception.do?id=720692

extracted from issue 

https://netbeans.org/bugzilla/show_bug.cgi?id=244697

The ClassMemberPanelUI$MyBeanTreeView (the navigator) holds 262k of items (VisualizerNode) which then holds the ElementScanningTask$RootStructureItem which holds tremendous amount of CSS' and JS' StructureItems. 

This seems to be a bug in the CLS's navigator implementation.

Please evaluate. Thank you.

I remove static functionality from ClassMemberPanelUI$MyBeanTreeView. so the GC can remove it after it is not referenced.
