[Cayenne - Dev mailing list]

Deadlock CayenneContextGraphManager when committing from two threads
--------------------------------------------------------------------

                 Key: CAY-1120
                 URL: https://issues.apache.org/cayenne/browse/CAY-1120
             Project: Cayenne
          Issue Type: Bug
          Components: Cayenne Core Library
    Affects Versions: 3.0
            Reporter: Ari Maniatis
            Assignee: Andrus Adamchik


How to reproduce:

* Try to commit some changes. This thread is delayed from completing the change by a lifecycle event which takes about 10 seconds to complete (in this case, contacting a credit card gateway)
* while this lifecycle event is running, have another thread try to commit changes to a different context.

Note that this is ROP, Cayenne 3.0 (from svn close to the M4 release)
