Is it correct when connectting to an port with no service listened

[tianyuanzhonglu]

    // Configure the client.
    EventLoopGroup group = new NioEventLoopGroup();
    Bootstrap b = new Bootstrap();
    b.group(group).channel(NioSocketChannel.class)
            .option(ChannelOption.TCP_NODELAY, true)
            .handler(new ChannelInitializer<SocketChannel>() {
                @Override
                public void initChannel(SocketChannel ch) throws Exception {
                    ch.pipeline().addLast(
                            new EchoClientHandler(firstMessageSize));
                }
            });

    // Start the client.
    // no service on port 8000
    b.connect("localhost", 8000).addListener(new ChannelFutureListener() {
        @Override
        public void operationComplete(ChannelFuture future)
                throws Exception {
            // not reached when exception occur
        }
    });
