Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Feature Pack for EJB 3.0             *
  ****************************************************************
  * PROBLEM DESCRIPTION: Java Persistence API (JPA) fails to     *
  *                      map an alias name to an entity type.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  A part of the metadata processing algorithm in OpenJPA had a
  race condition concerning the logic that maps entity aliases
  to the entity's class.  The following Exception is a potential
  indicator of this problem:
  
  <openjpa-2.0.0-SNAPSHOT-r422266:824454M fatal user error>
  org.apache.openjpa.util.MetaDataException: Could not locate
  metadata for the class using alias "MdrTestEntity". Perhap
  s you meant MdrTestEntity, which is a close match. This could
  mean that you have mis-spelled the alias, or that OpenJPA
  failed to properly load the metadata for the type whose
  alias is "MdrTestEntity". Registered alias mappings:
  "{MdrTestEntity=[class
  org.apache.openjpa.persistence.meta.MdrTestEntity]}"
  

Problem conclusion

• The race condition that created this problem has been updated
  such that concurrent access is properly synchronized.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.31.  Please refer to the Recommended Updates
