IPv6 in JRE 1.4.1 now works

With the final release of the 1.4.1 JRE/JDK (and perhaps with the help of the latest security download -- not sure), my IPv6 tests now all pass. Huzzah!

Here's my test program. If you have an IPv6 connection set up, they should all succeed.

import java.lang.*;
import java.io.*;
import java.net.*;

public class foo {
        public static void main(String[] args) {

                System.setProperty("java.net.preferIPv6Addresses", "true");

                DoATest("literal", "3ffe:1200:301b:0:2d0:b7ff:febe:e2a8");
                DoATest("A and AAAA host", "quack.kfu.com");
                DoATest("AAAA only host", "morpheus.kfu.com");

        }

        private static void DoATest(String testname, String host) {
                System.out.println("Starting test " + testname);
                try {
                        InetAddress ad = InetAddress.getByName(host);
                        System.out.println("Success: " + ad);
                        Socket s = new Socket(ad, 22);
                        System.out.println("Got connected.");
                        s.close();
                }
                catch(UnknownHostException e) {
                        System.out.println("Unknown host!");
                        return;
                }
                catch(IOException e) {
                        System.out.println("I/O Error!");
                        return;
                }
        }
}
