Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of the IBM WebSphere Application  *
  *                  Server "single" application classloading    *
  *                  policy                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Applications may incur classloading     *
  *                      problems or unexpected behaviors.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When an application server is configured with the "single"
  application classloader policy, WebSphere system applications
  and end-user applications share the same application
  classloader. The lack of isolation may cause unexpected
  behaviors or classloading problems whenever end-user and
  system applications provide the same open-source packages and
  resources.
  

Problem conclusion

• Apply APAR PI84518 to enable WebSphere system applications to
  load from their own application classloaders whenever the
  "single" application classloader policy is configured on an
  application server.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.0.8.  Please refer to the Recommended Updates
  page for delivery information:
