The following testcases fail on Windows Vista ONLY. Run was performed on AMD64 machine. The same testcases are passing on all other supported versions of windows:

api/java_net/MulticastSocket/MulticastSocket2011
api/java_net/MulticastSocket/MulticastSocket2004


with the following result:

MulticastSocket2011: Failed. Default TTL value is not equal to 1

MulticastSocket2004: Failed. Default TTL value is not equal to 1



To reproduce run the following code (port 50000 is hardcoded):

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

public class MulticastSocket2011 {
    public static void main (String[] args) {
        MulticastSocket soc=null;
        int port = 50000;
        int ttl;

        try {
            soc = new MulticastSocket(port);
        } catch (IOException e) {
            System.out.println("Can not create MulticastSocket instance:" + e);
            return;
        }

        try {
            ttl = soc.getTimeToLive();
        } catch (IOException e) {
            soc.close();
            System.out.println("Can not get TTL value:" + e);
            return;
        }

        soc.close();

        if (ttl == 1)
            System.out.println("OKAY");
        else
            System.out.println("Default TTL value is not equal to 1");
    }
}
