  * RECOMMENDATION:                                              *
  ****************************************************************
  If a JMS object handle is no longer valid but subsequently
  used, a NullPointerException will be thrown.  However, an
  IllegalStateException would more accurately reflect the
  failure.
  

Problem conclusion

• We now ensure an IllegalStateException is thrown to more
  accurately reflect the reason for failure.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.14.  Please refer to the Recommended Updates
