Alexey, please look at this.
Comment 3 Alexey Yarmolenko 2008-02-27 16:55:44 UTC 
I see2 different "points" of memory leaks in provided dump: 

First looks like caused by http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4903084
I need to investigate this issue to see if any workaround exists, because original bug was closed with NOT_A_BUG status.

And second goes thru xpath model. 

Nikita, please check the second one  and then reassign bug to me to fix the first.
Comment 4 Nikita Krjukov 2008-03-06 15:45:37 UTC 
Alexey, I've fixed the part related to the XPath model. 
I changed an XPath model class only.
Comment 5 Alexey Yarmolenko 2008-03-24 17:46:03 UTC 
Ok, my recent investigations:
Leak in XPath model was fixed by Nikita

Leak with 
private static sun.awt.im.CompositionAreaHandler sun.awt.im.CompositionAreaHandler.compositionAreaOwner->
sun.awt.im.CompositionAreaHandler@1a32d08-clientComponent->
org.netbeans.modules.bpel.design.DesignView@1daa485
Is a AWT problem with status WILL_NOT_FIX, because this path will be released as soon as other component will get focus
after closing design view.

Leak in decorationComponents was fixed as a part of another bug.

Closing this issue as fixed as soon as all listed leaks are removed.
