  ****************************************************************
  When PMI is used to get the statistics of the servant JVM, and
  if the same is not available then an internal connector
  exception is sent to the PMI code which intern will throw a
  ClassCastException.
  

Problem conclusion

• PMi code is modified in such a way that it will be aware of
  the Connector exceptions that might happen while accessing the
  Servant JVM's.
  
  APAR PM15742 is currently targeted for inclusion in
  Service Level (Fix Pack) 7.0.0.11 of WebSphere Application
  Server V7.0.
