APAR status

• Closed as program error.

Error description

• With a Object Relational Model involving an entity utilizing an
  embeddable id, in which that embeddable contains nested
  embeddable types, where at least two nested-embeddable types
  define a common persistent property name, then during
  Eclipselink's mapsid processing it can potentially select the
  improper basic accessor.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Eclipselink fails to properly process   *
  *                      nested embeddable ids with common       *
  *                      leaf property names                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Given a JPA using an embeddable id, where that embeddable
  itself contains embeddables, where two or more of these
  embeddable contain a common property name, the persistence
  unit processing can become confused and fail validation.
  

Problem conclusion

• The version of Eclipselink shipped with WebSphere has been
  updated to be able to handle this scenario properly.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.0.9.  Please refer to the Recommended Updates
