I'm just sending this to the dev list for the record in case people want
to recreate the logic I went through...

I figured this out by creating a mock socket impl and seeing what calls
were made on it from the RI, which were:
constructor
create
setOption id: 4 val:true
bind
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.DatagramSocketImpl;
import java.net.DatagramSocketImplFactory;
import java.net.InetAddress;
import java.net.MulticastSocket;
import java.net.NetworkInterface;
import java.net.SocketAddress;
import java.net.SocketException;
public class TestDGSocket {
private static class FakeSock extends DatagramSocketImpl {
public FakeSock() { System.out.println("constructor"); }
