I worked with a similar tool many years back to get our Java
applications running on
embedded devices.
The reason why it works so well is, that it can remove all the code from
the libraries your app doesn't use.
If somebody has a requirement for it they would probably just want to
run it over everything. People who don't
have a requirement for it probably don't really care if the jar has a
few mb or a few hundred kb.

While climbing some learning curves on the Android smartphone app platform, I
learned about ProGuard, http://proguard.sourceforge.net/ , which among other
things appears to shrink Jars by removing unused code, and doing various
optimizations. (It also can do obfuscation, but that I don't think would be
appropriate for an open source project :-) ).
Some optimizations / shrinkages are described here
http://proguard.sourceforge.net/#results.html
The run-time classes from Oracle's Java 6 shrunk 53 M to 22 M.
Apache Ant shrunk from 2.4M to 325K.
I wonder what it would do on our binary distributions...
