Found 1 deadlock.

Comment 3 Rafael Chaves

2003-02-19 11:11:11 EST

Philippe's scenario looks like a variant of bug 28671 (we don't have deadlock, 
but a huge number of messages being processed by the UI thread prevents a 
synchronous runnable to get executed).

Here, again, the refresh local operation has already finished but, differently 
than the other case, the *progress monitor* is blocked waiting for a chance to 
have a runnable executed by the UI thread (it was one of the resource change 
listeners in the other bug).

Johan, your dump does not include any workspace operation being executed, and 
it seems it is related to class loading. Have you logged it only in this PR?

Comment 4 Philipe Mulet

2003-02-19 12:24:36 EST

Actually, it only saw it "deadlocking" 10 minutes <g>, I killed it at that 
point... could have just taken an enormous amount of time.

Comment 5 Johan Compagner

2003-02-19 15:01:58 EST

i also reported it under bug 31074 yes (where i believe it somehow a 
classloading thing)

Comment 6 Rafael Chaves

2003-02-19 15:12:47 EST

So I recommend this bug to be marked as duplicate of bug 28671 (I do not have 
rights for doing it).
