> When the StreamPumper is copying data from the InputStream to the OutputStream, it would be safer to check for EOF instead of a read size greater than zero to protect against InputStream implementations that don't respect the contract as defined in Java core JavaDoc.
> Patch Included.  I took code from the copy method of the IOUtils class.
