I wrote a similar mail a few weeks ago (see below).
If you have the time to analyze and fix the problem or need some
support (I'm not an expert in this field, too) send me your ideas.

Betreff: how to use compression?
is there anyone who knows how to use the different compressors in IzPack?
I played around with "raw" and "bzip2" and different levels, for example
compile ... -c bzip2 -l 9
but I saw no (significant) influence on the installers size (only on the
time to build it).
For the application I want to pack, IzPack produces an 170 MB Jar.
(with InstallShield I got an 60 MB exe!)
