Not first hand :-) - but a web search found:

I don't know if gcj is available by default on 10.3 it wasn't 10.2.
Just so we can say we have all the fun toys I went ahead and built it. Appears like it will work anyhow at 10.2.

public class HelloWorld {

public static void main(String[] args) {
System.out.println("gcj Hello, World!");
}
}

[Black-box:~/gcc/bin] mjh% ./gcj --main=HelloWorld -Wall HelloWorld.java -o hello
[Black-box:~/gcc/bin] mjh% ./hello
gcj Hello, World!

I did a bootstrap build of gcc 3.4 including gcj.
One or two oddities in the build but not terribly difficult considering I know near to nothing about this build process.

I am putting the result on my iDisk if anyone just wants to start playing. I wouldn't rush though I just started the upload on a 56k modem and the zipped build result is 54M. Yeah, that took a while.

gcc.zip

I didn't see a license to include but I didn't really change anything, just muddled through the build.
Now maybe figure out to use it on Rhino like the page you indicated mentioned.
If anyone does figure out how to use it to generate comparable numbers I might be somewhat interested in seeing them.
