when upload multi-files in form-request, like:

<input name="file" type="file" id="uploadFiles" multiple="multiple" />

then, in /org/kohsuke/stapler/RequestImpl.java#parseMultipartFormData() method, multi files will have the some feildname, and last pared file will cover the prior parsed file:

private void parseMultipartFormData() throws ServletException {
    if(parsedFormData!=null)    return;
    // use map to store fileItem, and use feildname as key.
    parsedFormData = new HashMap<String,FileItem>();
    parsedFormDataFormFields = new HashMap<String, String>();
    ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory());
    try {
        for( FileItem fi : (List<FileItem>)upload.parseRequest(this) ) {
            parsedFormData.put(fi.getFieldName(),fi);
            if (fi.isFormField()) {
                parsedFormDataFormFields.put(fi.getFieldName(),fi.getString());
            }
        }
    } catch (FileUploadException e) {
        throw new ServletException(e);
    }
}

I am not sure where should I fix this problem, front-end or back-end? Anyone have some suggests?

Besides, this problem occurs in jenkins, when try to modify it's FileParameter plugin.
