That's not true. Although the class file might only have 410 bytes, you 
still need a runtime (JRE) of about 70mb to let it run. You can also 
dynamically link to libgcj (well, not on Windows), then your binaries 
will be only a couple of kb's.

The things I know are:
- Pack the binary (e.g. UPX [1])
- Exclude parts of the class library (See JNC [2])
