OFBIZ-5048 I proposed to change the file item entry from ByteBuffer to FileItem for easier access to the file temporarily stored on the server. This broke existing functionality and was reverted by me today.
I now propose to add a FileItem entry to the multipart map to allow direct acces to the file item and remain compatible with the services using this functionality.
A patch will follow.
I also propose to backport this to the 17.12/18.12 branches to provide the functionality which was reverted.
