* RECOMMENDATION:                                              *
****************************************************************
Due to a code defect, there is a code path which accesses an
object without validating it is not a null object. As a
result, if the object is null, NullPointerException is
caught.

Problem conclusion

With this fix, the code checks an object being accessed is
valid.

The fix for this APAR is currently targeted for inclusion in
fix pack 6.0.2.43, 6.1.0.33, and 7.0.0.13.  Please refer to
