I get ObjectCollectedException from time to time (M3, Mandrake 9). These seem to occur in
every edition, but M3 is (seems) worse. Along with these exceptions the debugger
in eclipse hangs. Screen refresh works, but I can't do anything.

I think the stack trace is a red herring. The code in JDIModelPresentation
handles the exception gracefully and writes the stack trace to the log.
I run on Mandrake 9 and I just had the debugger hang this morning.
Fortunately, it happened while I was debugging the debugger, so I was able
to suspend the Main thread and see what was going on. In my case, the Main
method was stuck in a call to java.io.File#exists() which is called by the
launch config framework to validate the config file before launching.
I don't know why this call would block.

Do you have any information about what file was being accessed?

Yep. The file was a launch configuration file in the workspace metadata -
something like Hello.launch.

Ok, that seems irrelevant. I got it back to a working state by replacing
most stuff I have updated from cooker the last two days. Among the
last libraries removed before the thing started working was libglib2 and
libgk+-x11+.
I also had an error message about failing to initialize drag and drop when
I left the hanging session for a while. I am quite sure I did not try to do
drag-n-drop at the time. Does that give a clue?
