Stripped? You should be seeing 1-2MB, depending on target and options.

That's incorrect.
I assuming you mean a program to do "System.out.println(...)" of
something. This requires loading/initializing System, Runtime,
Properties, plus much of java.util and java.io. All of these classes will
be statically linked by gcj.

Try "java -verbose:class HelloWorld" for comparison. I get something like
240 class loaded and 74 initialized with JDK 1.3.1.
You can blame Sun for this design. It's not gcj's fault.
