FWIW, I tried it on Mac OS X 10.5.6, Java 1.5.0_16. Inside the LAN, I
saw "Connection refused" for ports without a listener; I saw "true" for
ports with a listener. I used netstat to see the results. I also got
warnings about unauthorized connections from the application firewall.

You might use netstat to see the internal state of whatever port is
giving anomalous results.

<code>
import java.io.*;
import java.net.*;

public class KJTest {
    public static void main(String[] args) throws Exception {
        int port = args.length > 0 ? Integer.valueOf(args[0]) : 8080;
        Socket s = new Socket("localhost", port);
        System.out.println(s);
        System.out.println("connected to: " +
        s.getInetAddress().getHostName());
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(
        s.getOutputStream()));
        bw.write("hello world\n");
        System.out.println("data written");
        bw.close();
        System.out.println(s.isClosed());
    }

}
