APAR status

• Closed as program error.

Error description

• When using the jpa-2.0 feature, deserializing a ResultList
  object may result in the following ClassNotFound exception:
  org.omg.CORBA.MARSHAL: class
  org.apache.openjpa.lib.rop.EagerResultList not found (no
  codebase provided):  vmcid: 0x0 minor code: 0x0  completed:
  No
  
  The reason this problem occurs is that OpenJPA returns an
  implementation class from the getResultList() method and
  upon deserialization, that class isn't visible to the app
  classloader. In order to fix this issue, we have exposed the
  org.apache.openjpa.lib.rop package.

Problem conclusion

• The JPA manifest file has been updated to expose the
  org.apache.openjpa.lib.rop package which allows users have
  access to the missing class.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.7.  Please refer to the Recommended Updates page for
