I'm having trouble debugging a main() inside an inner class.  Here's the
code:

public class TestInner{
    public TestInner() { }

    static public class Inner{
        public static void main(String args[]){
            System.out.println("some output");
        }
    }
}

It compiles fine, and runs from the command line (java TestInner$Inner)
but I can't run/debug it from JBuilder.  I get a message: "Cannot
determine runnable file".  I can't set TestInner$Inner to be the default
runnable, even if I edit the jpr file by hand.  This works in J++.  Any
ideas?

P.S. If you're wondering why the hell I'd do this, check out Bruce
Eckel's excellent book _Thinking_in_Java_.
