Well, this is what jdk-1.1 jar does:

[14:18] lectric(pts/8):~% dd if=/dev/zero of=foo bs=1M count=1
1+0 records in
1+0 records out
[14:18] lectric(pts/8):~% jar cvf foo.jar foo
adding: foo (in=1048576) (out=1033) (deflated 99%)
[14:18] lectric(pts/8):~% ls -l foo.jar
-rw-rw-r-- 1 flux flux 1417 Jan 6 14:18 foo.jar

And that's the official jdk by Sun. Perhaps things have changed between 1.0
and 1.1? Netscape 4.7 handles it ok. I suspect that the original package
made for Debian might be created without compression, but still du -b of the
contents after extracting the original postgresql.jar is more than the size
of the original .jar.. (160768 bytes compared to 143506 bytes)
