> When not selecting any file to upload in a file input, Struts does not ignore the 0 byte
file returned by jakarta FileUpload.
> This means that a file is injected in the action even if nothing was uploaded. 
> In webwork the check was done in the constructor of  com.opensymphony.webwork.dispatcher.multipart.JakartaMultiPartRequest:
> else if (item.getSize() == 0) {
>   log.warn("Item is a file upload of 0 size, ignoring");
> }
> In struts the parsing of the request moved from the constructor to a parse method but
the above check disappeared.
> Additionally this behaviour is inconsistant with the "pell" implementation that ignores
0 byte files.
