  ****************************************************************
  The SinglePathClassProvider was not removing itself from the
  cache when it was disposed of, for example when an application
  is stopped. When the application was restarted, the cached
  SinglePathClassProvider was used instead of creating a new
  one.  Any new packages in the provider were not added to the
  package list.  Trying to use a class or resource in one of the
  new packages resulted in it not being found.
  

Problem conclusion

• We now correctly remove the provider from the cache at
  disposal time.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 6.0.2.35.  Please refer to the Recommended Updates
