SECJ0128E: An
unexpected exception occurred during Trust Association. The

****************************************************************
* 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.
