PH23010: NullPointerException can occur when JAXRS application is restarted without also restarting the containing server.

APAR status

• Closed as program error.

Error description

• A NullPointerExeption can occur when a JAXRS applcication
  containing async activity on the server is restarted.  This
  will only occur if the corresponding server is not restarted
  when the application is restarted.   The NullPointerException
  in the logs may be similar to the following:

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server with applications using JAXRS.       *
  ****************************************************************
  * PROBLEM DESCRIPTION: If a JAXRS application involving        *
  *                      async activity on the server can        *
  *                      experience a NPE if                     *
  *                      the application is restarted.           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  If a JAXRS application involving async activity on the server
  can experience a NullPointerException if the application is
  restarted and re-used without the corresponding server being
  recycled.
  

Problem conclusion

• The problem has been resolved by ensuring the MetaData
  associated with the JAXRS application is cleaned up when the
  application is stopped.  This will make the behavior match
  the
  current behavior when the entire server is stopped and
  restarted.
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.4.  For more information, see
