Description _ rkubacki 2006-10-23 11:11:19 UTC 
dev build from Oct 20 (not retouche), JDk6b98

I opened Hudson project from java.net, opened hudson.Util class and did find
usages on nullify() method. One of the usages is
Maven.DescrpitorImpl.configure() and NbEditorDocument of its source file is now
strongly held in memory through this refrence chain:

Comment 1 Jan Lahoda 2007-03-19 10:49:23 UTC 
Radim, does this still happen after the Retouche merge? Thanks.
Comment 2 Petr Nejedly 2007-03-19 14:57:00 UTC 
Harder to verify (because of issue #97201)
Comment 3 Jan Lahoda 2007-03-22 09:06:52 UTC 
Should be investigated for NB6.0 anyway.
Comment 4 Jan Becicka 2007-09-11 12:45:30 UTC 
This issue is not valid in 6.0. org.netbeans.modules.java.JavaEditor does not exist any more.
