Well that line actually only gets an error because the file (empty.txt) never gets uploaded to the "work" directory. My hunch was that the Struts FileUploadInterceptor was not copying the file over if the length of the file was "0". So the exception is caused because the file simply doesn't exist when in technically there should be a 0 byte file there.
