Hi,
I'm using eclipselink 2.5.0 with weblogic 12.1.3, the application works just fine but in the weblogic log a warning pops up. Debugging, I found out that the warning rises when a ServerSession is created and the changeset contains a class provided by a persistence unit configured with the jar-file tag. It only happens when the session is Server type, client type is ok. The problem is in the WriteLockManager class, the descriptor from the changeSet object is null and after 2 attempts to get it is still null and finally when it's used the nullPointerException is thrown.
The warning is the following after finest log configuration:
