A warning message should be logged when a down level enhanced Entity is encountered.

                 Key: OPENJPA-1707
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1707
             Project: OpenJPA
          Issue Type: Improvement
          Components: kernel
    Affects Versions: 2.0.0
            Reporter: Rick Curtis
            Assignee: Rick Curtis


Currently when PCEnhancer is called to enhance an Entity that was previous enhanced it will
simply noop and move on. It could be smarter and use the PersistenceCapable.pcGetEnhancementContractVersion
to detect and when an Entity has been enhanced with an older version of the enhancer and log
a warning message. A similar change would also need to be made to PCClassFileTransformer.needsEnhance
to perform the same sort of logic at runtime.

This would be particularly helpful in the case where an application was compiled/enhanced/packaged
and a bug was fixed in the enhancer but the pre-packaged app still has the bad bytecode.
