Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server V6.1 and V7.0 using the Performance  *
  *                  Servlet                                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: Null Pointer exception is seen in the   *
  *                      browser when the Performance Servlet    *
  *                      is accessed with the version=5 option   *
  *                      enabled.                                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Performance Servlet needs the NodeAgent to be active to
  communicate with the other servers. When NodeAgent is not
  available or is shutdown, then a NullPointerException is seen
  in the browser. Though the Symptom is expected, the exception
  in the browser is not correct.
  

Problem conclusion

• Code has been updated to handle the exceptions or divert  them
  to SystemError and proper suggestions are given in the browser.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.17 and 6.1.0.37.  Please refer to the
  Recommended Updates page for delivery information:
