During a servlet request, the customer could encounter a
NullPointerException when calling getHeader() if a previous
servlet request handled a file upload and contained an embedded
FileItem.

    ... 72 more

Problem conclusion

A class in the commons fileupload library was recently patched
to address another issue, but was missing an implementing
interface, which caused this regression.  This fix adds in the
interface, which resolves the issue.

The fix for this APAR is currently targeted for inclusion in fix
pack 18.0.0.1.  Please refer to the Recommended Updates page for
