I think the problem is in authbind: it only supports IPv4.

Try this:

 $ authbind --depth 2 java -Djava.net.preferIPv4Stack=true ListenTest
ServerSocket[addr=localhost/127.0.0.1,port=0,localport=80]

Andrew.

import java.net.*;

public class ListenTest {
    public static void main(String[] args)
        throws Throwable {
        ServerSocket s = new ServerSocket(80, 0, InetAddress.getByName("localhost"));
        System.out.println(s);
    }
}
