  ****************************************************************
  The leak happens when WebSphere Application Server code
  (which is not loaded by the application classloader) keeps a
  reference to an application class.
  As there is an "external" reference to an application class,
  which at the same time points to its classloader (application
  classloader), there is a strong "live" reference to the
  classloader and it cannot be garbage collected.
  

Problem conclusion

• The memory leak has been fixed by changing the reference to
  the context classloader to a WeakReference.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.17.  Please refer to the Recommended Updates
