Problem conclusion

• The fix for this APAR changes the OpenJPA implementation
  and involves an update to the third-party source. See
  https://issues.apache.org/jira/projects/OPENJPA/issues/OPENJPA-2
  882.
  
  This fix is currently targeted for WebSphere Application
  Server 9.0.5.14, 8.5.5.23. For
  more information, see 'Recommended Updates for
  WebSphere Application Server':
