Not true in this case - FileUploadBase is not involved, as I keep trying
to explain. IIRC, there is such a check in Tomcat's standard HTTP
handler, since the standard handler needs to know how big a buffer to
get for the entire request. You have apparently made the invalid
assumption that the -1 check can only exist in one place, when in fact
it is rather pervasive.

The proper fix is for your webapp to actually use commons-fileupload,
which it is not currently doing.

BTW, you shouldn't use the unqualified term "Apache", unless you're
referring to the open-source software development organization, not any
particular product of that organization. For the subject of this
discussion, just refer to Tomcat.
