This bug has been around in one form or another for many many months.
The problem seems to be related to the header written before the actual
data is placed in the zip file. I have been meaning to get around
to fixing it but I just have not had the time to write up all the test
cases needed to fix it once and for all. If you want to jump in and
take a whack at it, the problem is in the class ZipOutputStream.java!
