Description _ rkubacki 2006-10-23 10:47:54 UTC 
dev build from Oct 20 + profiler build 061020, JDk6b98

I opened nbbuild+all projects, did few actions in IDE including opening profiler
TC and Attach profiler wizard and then closed everything but all project
instances and their associated data are held in memory (cannot get below 120MB
of used memory in Java heap).

The biggest problem seems to be this rerefence chain -

Comment 1 _ rkubacki 2006-10-23 10:53:45 UTC 
These projects are probably released only if I open attach wizard again (and
model gets updated).
Comment 2 Tomas Hurka 2006-11-20 12:28:49 UTC 
No, ProfilingSupport listens to OpenProjects.PROPERTY_OPEN_PROJECTS property change and updates 
model as soon as it receives this property change.
Comment 3 Tomas Hurka 2006-11-21 15:19:26 UTC 
problem is that javax.swing.JList$AccessibleJList$AccessibleJListChild holds old DefaultComboBoxModel 
with opened projects. It does not listen to "model" property change and therefor do not reflect model 
change, when projects are closed. I will try to investigate if this is Swing bug.
Comment 4 Tomas Hurka 2007-01-08 10:32:51 UTC 
Should be fixed in trunk.
Comment 5 Alexander Kouznetsov 2007-09-08 11:45:17 UTC 
rkubacki, could you please verify this issue?
