Description Samaresh Panda 2007-04-25 01:51:10 UTC 
While investigating http://www.netbeans.org/issues/show_bug.cgi?id=98405 I can
see that HintsUI keeps a strong reference to the UI.

This leads to memory leak, while opening/closing of schema files.
Comment 1 Samaresh Panda 2007-04-25 02:02:08 UTC 
Additional Information:
EntPack introduces a multi-view schema editor, which in turn brings in
SchemaModel and AXIModel. Opening/Closing a schema should discard these models
and the multiview elements as well.

I have a heap dump but the size it about 50MB, hence I'm attaching these screen
shots of path to GCs for some items.

Comment 5 Jan Lahoda 2007-04-25 11:07:34 UTC 
Ok, I was wrong, sorry. The patches so far fix holding of the "last" editor in
java/source and editor/hints, but not when working with multiview editors :-(.
Anyway, at most one component is held (->P3), not necessarily the last one
(->P2). I will try to do something about this for M10 - I would prefer one place
that would do the magic making the listeners simpler than creating
WeakReferences everywhere. Comments?
Comment 6 Samaresh Panda 2007-04-26 20:02:46 UTC 
I'm not sure why this was made a P2. IMO, this should be fixed for Preview as
this impacts a high priority issue 98405.
Comment 7 _ rkubacki 2007-04-26 21:03:53 UTC 
This should be fixed together with #100752 (you file duplicate of this recently
too). What build are you using (every good bug report should contain this
information)?
