  ****************************************************************
  If a Web Service provider is configured to support both
  WS-Atomic Transactions and WS-ReliableMessaging then a
  java.lang.ClassCastException occurs when the provider is
  processing the response to a request containing a WS-AT
  context.
  It should be noted that WS-RM and WS-AT cannot be used on the
  same request by design, however it should be possible for a
  Web Service provider to be configured to support both WS-AT
  and WS-RM so that either of those qualities of service are
  available on a mutually exclusive basis.
  The ClassCastException occurred because the WS-AT component
  inserted a plain OMElement directly into the SOAPHeader rather
  than a SOAPHeaderBlock.  Later processing by the WS-RM
  component cast the SOAPHeader's child directly to a
  SOAPHeaderBlock.
  

Problem conclusion

• The WS-AT component was modified to add a SOAPHeaderBlock,
  rather than a plain OMElement, to the SOAPHeader.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.5.5.16 and 9.0.5.1.  Please refer to the
  Recommended Updates page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• The error occurs when using the default deferred registration
  optimization for WebSphere Application Server to WebSphere
  Application Server WS-AT.  This optimization can be disabled
  by specifying a new Transaction Service Custom Property with
  name DISABLE_WSTX_DEFERRED_REGISTRATION and value true
