Why am i getting this error running 'net' module node.js

Question

I am using .net modular and opening tcp port on 6112.

var net = require('net');
    var server = net.createServer(function (socket) { //'connection' listener
    });
server.listen(6112, function () { //'listening' listener
    console.log('server started');
});

On the same machine i start a java socket in main.

public static void main(String[] args) {
        // TODO Auto-generated method stub

        try {
            System.out.println("Connecting...");
            Socket socket = new Socket("localhost", 6112);
            System.out.println("Connected");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

I get this exception,

C:\Users\Mustafa\WebstormProjects\Node.Js>node hello.js
server started

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: read ECONNRESET
    at errnoException (net.js:884:11)
    at TCP.onread (net.js:539:19)

Is this like a bug or something, cause if once i get through this bug, I will be good thanks.

I haven't used the debugger cause as Ryan said it him self a year ago that it is still shitt.

You need to listen for errors on the socket. Node has the default behavior that when something does .emit('error'), if there are no error handlers attached, it will throw the error instead, thus crashing the application.

var server = net.createServer(function (socket) {
    socket.on('error', function(err){
        // Handle the connection error.
    });
});
