Alton Idowu commented on CXF-1839:
----------------------------------
Go ahead and close it. Unfortunately, we have been unable to consistently
reproduce it.
> Weird deadlock between CXF and spring on WAS.
> ---------------------------------------------
>
> Key: CXF-1839
> URL: https://issues.apache.org/jira/browse/CXF-1839
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 2.1.1
> Environment: Windows XP, Ubuntu 7.04, jdk 1.5.0_09, CXF 2.1, spring
> 2.0.2, quartz 1.6.1, WAS 6.1
> Reporter: Alton Idowu
> Assignee: Benson Margulies
>
> We are using quartz to make periodic calls to different web services. Every
> once in a while we get a deadlock that eventually crashes our WAS server.
> The stack trace below does not make sense to me. it appears that worker-5
> has a lock on the LinkedHashMap containing the spring singleton beans that
> worker-7 is attempt to access in the synchronized configurebeans method. And
> worker -5 is waiting for worker-7 to exit the configurebeans method. I took
> a quick look at the code and it didn't seem that worker-5 kept a reference.
> It would be great if someone point us in the right direction to solve this.
> Let me know if you require additional information....
