Is this code not there?

	// Accumulate the first intersection of the given ray with this group
	// This function is used both for primary and shadow rays.
	public Intersect intersect(Intersect i, Ray ray) {
	    double l = bound.ray_sphere(ray);
	    if (l >= i.lambda) return i;
	    // Loop over the list of child nodes, accumulating the result.
	    ListIterator it = objs.listIterator(0);
	    while (it.hasNext()) {
		Scene scene = (Scene)it.next();
		i = scene.intersect(i, ray);
	    }
	    return i;
	}

Maybe there's something wrong with my declaration of that function.

It should work for gcj and gij. Can you put it up so that I can see the errors 
from Sun's Java compile and try to fix them. I'll have a go at installing 
J2SE as well...
