  *                      listener, a NullPointerException        *
  *                      might be thrown.                        *

  * RECOMMENDATION:                                              *
  ****************************************************************
  If the servlet listener code implements the Java Persistence
  API (JPA), there is a potential that a NullPointerException is
  caught while processing the JPA code. This
  NullPointerException is caught during processing the listener
  when it is fired by removeAttribute method of
  HttpServletRequest object.
  

Problem conclusion

• With this fix, the code was modified not to use the
  removeAttribute method to avoid the NullPointerException.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.7.  Please refer to the Recommended
  Updates page for delivery information:
