Description _ rkubacki 2004-12-10 11:12:08 UTC 
dev build from Dec 8, JDK5.0u1-b06, Linux

On of the contributors to issue 51769 - one of
threads running in JVM is AWTAutoShutdown that
holds JWindow instances with peers. From these
peers it is possible to get to our components and
related data like FormDesigner. Probably the
reason is that we do not dispose the component
when it is no longer needed.

Comment 1 _ rkubacki 2004-12-10 16:58:01 UTC 
Almost all these windows are tied to
org.netbeans.modules.form.palette.ScrollPopupMenu. The rest are
probably live windows. I guess this is something specific to this
class (also it can be a multiview problem).
Comment 2 Tomas Pavek 2005-01-04 10:18:51 UTC 
We will check what we can do with the ScrollPopupMenu - not to
reference the whole form editor.
Comment 3 Jan Stola 2005-01-07 09:43:12 UTC 
The Window object used by ScrollPopupMenu wasn't correctly
disposed (the Window was only hidden). It is fixed by now.
