****************************************************************
During class transformation, OpenJPA sets a temporary context
classloader. However, the temporary classloader was not cleaned
up and replaced after transformation. This change was delivered
to later OpenJPA versions and is being backported to OpenJPA
2.2.3

Problem conclusion

The fix for this APAR changes the OpenJPA implementation and
involves an update to the OpenJPA thirdparty bundle. See
https://issues.apache.org/jira/browse/OPENJPA-2575
The fix for this APAR is currently targeted for inclusion in
Service Level (Fix Pack) 9.0.0.8 of WebSphere Application Server
version 9.0, Service Level (Fix Pack) 8.5.5.14 of WebSphere
Application Server version 8.5, and in fix pack 18.0.0.1 for
WebSphere Application Server Liberty.  Please refer to the
Recommended Updates page for delivery
