Error description

  • When trying to read incoming session data, particularly from a
    Webseal-authenticated user, WAS security auditing code throws
    the following NullPointerException:
    
    [9/24/12 12:07:28:663 PDT] 0000005c WebAuthentica E
    SECJ0128E: An
    unexpected exception occurred during Trust Association. The
    exception is java.lang.NullPointerException at

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server who uses audit function as well as   *
    *                  WebSeal Trust Association Interceptor       *
    *                  (WebSeal TAI)                               *
    ****************************************************************
    * PROBLEM DESCRIPTION: When audit function is enabled,         *
    *                      WebSphere Application server throws     *
    *                      NullPointerException                    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Audit code assumes http request is always non-null.  However
    WebSeal TAI could send null http request and caused
    NullPointerException.
    

Problem conclusion

  • Code is updated to check http request to avoid
    NullPointerException.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.29, 8.0.0.7 and the release after 8.5.0.2.
