  The WebSphere Application server plugin component would use
  the default 503 message instead of passing the custom message
  back to client.
  

Problem conclusion

• The plugin component will retry another server when it
  receives a 503 message but if the last server attempted sends
  a custom 503 message, it will be passed back to the client.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 6.0.2.35, 6.1.0.27, 7.0.0.5.  Please refer to the
