jagub zhang commented on FILEUPLOAD-195:
----------------------------------------

I think it is a very old problem about j2ee.
commons-upload get total size of upload using ServletRequest#getContentLength()

Interface ServletRequest#getContentLength() return a int value.
on j2ee javadoc:
  an integer containing the length of the request body or -1 if the length is not known

The max value of int is 2147483647, it is less then 2gb(2147483648).
then it return -1
