Hello,
We have been seeing some intermittent issues with the parallel
classloader. I do not want to jump to any conclusions and say this is a
bug w/ the classloader, but we are getting deadlocked threads, pretty
randomly, when launching the server. I was wondering if anyone had
experienced this issue or if you could review the attached thread dump and
give me some feedback.
There is no associated log file for the time the deadlock was occurring, I
am working on getting that. In unrelated log files I saw some concurrency
exceptions, non-thread safe access to lists basically. I believe that
issue has been corrected in the source code, and I am not sure the
concurrency exception has anything to do with the deadlock occurring during
classloading.
Personally I am of the belief that unsafe maps / lists could possibly cause
the classloader to deadlock.
I can put the full dumps in a ticket, I just hate to open another
classloader ticket.
I don't see a deadlock in the provided stack trace.
