I think you should be able to just open the bundle .app?
'man open' might be helpful.
Greg Guerin details on his pages how to set the bundle properties to a shell script executable that turns around and invokes the JavaApplicationStub. A neat and possibly handy trick here.
Assumption as well is that you mean Mac OS X and not Mac OS.

The following below is the shell command from my Combined application. The gist is you Runtime /bin/sh. The rest is sort of how my application wraps Runtime invocations for you if you choose to use it. IOW bit of a plug for my application although its just free stuff I've messed with.
Other stray thoughts that may or may not be of any use would be that Terminal itself is AppleScriptable. You might be better off with a small AppleScript than a java application for this. Or as Greg Guerin has been pointing out. You can also directly run small AppleScript's with the OSA commands via Runtime which might be of some use to you.
import utillib.exec.ExecutableInterface;
import utillib.exec.RuntimeExecutable;
public class shell {
// -c to pass shell a command
public static void main(String [] args) {
String [] shargs;
if (args.length == 0) {
System.out.println("shell: Missing or invalid arguments");
return;
}
ExecutableInterface shellexec = new RuntimeExecutable("/bin/sh");
shellexec.exec(args);
}
}
