Below is the code which I run to find if the port 7054 is free and it always display as free on console. However, when i pass this port to run firefox it gives error, port binding can anyone help me on this. Thanks

            //        System.out.println("Free Port: "+i);
            return i;

    throw new RuntimeException("Could not find an available port between"

                // can never happen
            }
        }
    }
 }

 public void portReuse() {
    try {
        ServerSocket socket1 = new ServerSocket();
        ServerSocket socket2 = new ServerSocket();
        ServerSocket socket3 = new ServerSocket();
        int port = 7054;

        socket2.setReuseAddress(true);
        socket2.bind(new InetSocketAddress("127.0.0.1", port));

        Thread.sleep(Long.MAX_VALUE);
    } catch (Exception e) {
        e.printStackTrace();
    }
 }

 public static void main(String agr[]) {
    PortFinder pf = new PortFinder();
    pf.findFreePort();
 }

}

Unless this is some esoteric formatting convention I've not heard of, you might want to think about using your IDE's pretty-format features to fix that second code snippet of yours. — BoltClock

I think you have to add the below host entry to your hosts file.

127.0.0.1 localhost

It worked for me
