Description Antonin Nebuzelsky 2005-09-08 15:29:19 UTC 
When you leave an open conversation, it disappears completely from the UI (not
listed under Conversations node anymore), but there are tons of various
org.netbeans.modules.collab.* instances left on heap. See the attached
OptimizeIt screenshot.

The leak may be more complex than just one leaking instance keeping the others,
because looking at some of the objects in detail I saw some of them listening in
various listener chains.

The size of the leak is quite large, especially if you share files through the
conversation.

First opened conversation with a particular contact leaked ~1.2MB, subsequent
opened conversations leaked ~300kB. After I shared a small project through the
conversation (with 2 files in it, which I then opened in the remote IDE) the
leak raised to ~3MB.

This should be fixed to Beta -> P1.

Working on it.
Comment 4 Petr Nejedly 2005-09-14 15:35:16 UTC 
I found several places that caused this leak.
Most of them is fixed now, but there seems to be a remaining leak in the service
library. Now only the first conversation is leaked through
XMPPConferenceService/XMPPConference, all the subsequent conversations are freed
correctly. I'll file a separate issue for service library.
