java.net.Socket.getTrafficClass() permanently throws SocketException when an
attempt is made to get traffic class for a socket under Windows 2000. The
problem is similar to one described in 4511783, however this time
getTrafficClass() works fine on Solaris, but throws an exception on Windows.
This is illustrated by the following example:

--------------- Test.java -----------
import java.net.*;

public class Test {

    public static void main(String args[]) {
        Socket soc = new Socket();
        try {
            int tc = soc.getTrafficClass();
            System.out.println(tc);
        } catch (SocketException e) {
            e.printStackTrace(System.out);
        }
    }
}
