    ****************************************************************
    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
    page for delivery information:
