Description

A ProgressListener doesn't always get informed when a new part is found by the MultipartStream. This is most easily replicated by uploading small files (a few bytes in size). The listener will be correctly informed about the content length and the total bytes uploaded but it will be told that it is currently working on item 0. This causes an issue when this count is used to detect a form has been submitted with no file.

This has a simple fix to the org.apache.commons.fileupload.MultipartStream (patch will be attached), when the items count is incremented the listener needs to be notified.
