  When calling methods the API methods of a PageContext object,
  an IllegalStateException is thrown if the session object has
  been invalidated. An example exception is the following:
  Exception: SRVE0777E: Exception thrown by application class
  'com.ibm.ws.session.http.HttpSessionImpl.getAttribute:200'
  java.lang.IllegalStateException: The following session is not
  valid! sessionID
  at
  com.ibm.ws.session.http.HttpSessionImpl.getAttribute(HttpSession
  Impl.java:200)
  ...
  These methods should operate over the page, request, session
  and application scope.
  

Problem conclusion

• The JSP container was modified to handle the
  IllegalSateException in PageContext API methods if a session
  has been invalidated.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.12 and 8.5.5.8.  Please refer to the
