I posted a Patch to this Mailing List a few days ago, but nobody seems to be
interested in it. I got an Error in 1.1b even when i just forwarded a
Multipart-Request to a JSP-Page.It's a bug in the RequestProcessor
doForward() Method. There the MultipartRequestWrapper must be unwrapped to a
normal HttpServletRequest-Object. See the patch
