Consider that java.lang.String is vital to the runtime, and the example
you've tried directly initializes java.lang.System, java.io.PrintStream,
and indirectly needs Properties, Runtime, OutputStream, and a whole host
of other classes.  You may be able to trim down the size somewhat, but
it'll never be as small as those three classes you mention.

How small do you require?  I suspect that with some careful hacking a 2x
reduction of HelloWorld.exe could be achievable.  However if you need
100KB standalone executables, Java is probably the wrong language for you.
