  *                      different tables, but share the same    *

  ****************************************************************
  If an ID (primary key) is declared on a superclass of two
  entities the value must be unique for both of them. Whether
  the entities map to different tables is not taken into account.
  

Problem conclusion

• To resolve this problem the persistence provider code has been
  updated and will only require the ID value to be unique for
  entities which share a table. More specifically the shared
  table must contain the ID (primary key).
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.1.0.31.  Please refer to the Recommended Updates
