At the same time 7zip has been able to extract the certificate so the
archive itself has been readable for 7zip.  This indicates the archive
was correct but you've run into an issue with the code that is
extracting the jar.

I'm not sure I understand which jar you've expanded.  The one created by
Ant or the one created by 7zip.

If it has been the original archive, this also means the jar tool has
been able to read the archive.  This would hint the problem is within
the code you use to read the archive.
