PM30346: INVALIDSTATEEXCEPTION WHEN RUNNING OPENJPA APPLICATION

APAR status

• Closed as program error.

Error description

• When you run OpenJPA application in WebSphere Application
  Server V7 you might get an InvalidStateException exception.
  .
  The problem is related to this OpenJPA defect:
  https://issues.apache.org/jira/browse/OPENJPA-1911
  

Local fix

• N/A.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of the Java Persistence API       *
  *                  (JPA) 2.0 feature of the IBM WebSphere      *
  *                  Application Server V7 Feature Pack for      *
  *                  OSGi Applications and Java Persistence API  *
  *                  (JPA) 2.0 who attempt to merge (that is     *
  *                  EntityManager.merge) a JPA entity which     *
  *                  has been serialized and contains a compound *
  *                  primary key (that is, uses @IdClass).       *
  ****************************************************************
  * PROBLEM DESCRIPTION: InvalidStateException can occur when    *
  *                      merging a serialized JPA entity which   *
  *                      contain a compound primary key.         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Take an entity which contains a compound primary key,
  specifically the entity uses @IdClass.  When an instance of
  this entity is serialized (for example, part of a remote method
  call), if a user attempts to merge the instance (that is,
  EntityManager.merge), it could result in an
  InvalidStateException.
  

Problem conclusion

• With this fix, code has been added to ensure that a JPA entity
  which contains a compount primary key can be properly merged
  after that entity has been serialized.
  
  The fix for this APAR is currently targeted for inclusion
  in Fix Pack 1.0.0.5 for Feature Pack for OSGi Applications and
  Java Persistence API 2.0.
