Description Tomas Zezula 2004-09-10 08:07:32 UTC 
The deadlock happens on Windows when user creates
project, closes it, externally deletes it and
create new one with the same name on the same
place. The creation of new project must be quite
fast :-)

I am not use who is responsible for this deadlock.
The deadlock is casused by (File externally
modified, reload dialog and Scanning classpath
dialog).

Are our customers developers or maniacs? ;-)
Comment 3 Milan Kubec 2004-09-10 12:56:38 UTC 
I'm no a maniac and I managed to reproduce the problem (and I wasn't
that fast as tomas :)
Comment 4 Jesse Glick 2004-09-10 16:50:15 UTC 
BTW Tomas please use attachments rather than pasting text inline...
formatting gets screwed up.
Comment 5 Martin Matula 2004-09-24 11:16:39 UTC 
Another deadlock related to the fact that we need to touch MDR in
createCookie - this one caused by our hack to fix the issue - the
overriden getCookie method starts a transaction in document lock. This
one and issue 49369 should be fixed together by implementing Yarda's
suggestion.
Comment 6 Martin Matula 2004-09-29 16:54:40 UTC 
Fixed.
