    Description

      I've been seeing Tomcat 5.5 lock up with this message:

      WARN - ThreadPoolAsynchronousRunner$DeadlockDetector.run(429) |
      com.mchange.v2.async.ThreadPoolAsynchron
      ousRunner$DeadlockDetector@547c38 – APPARENT DEADLOCK!!! Creating emergency
      threads for unassigned pend
      ing tasks!

      I found on the net that this is related to c3p0 pooling software and is fixed
      in c3p0 0.9.0.2. I see that xwiki is using c3p0 0.8.

      Do you think this is right?
      thanks,
      ==Leonard
