The code snippet:

        Bootstrap b2 = new Bootstrap();
        b2.group(childGroup)
                .option(ChannelOption.TCP_NODELAY, true)
                .channel(NioSocketChannel.class)
                .handler(new ChannelInitializer<SocketChannel>() {
                    @Override
                    protected void initChannel(SocketChannel ch) throws Exception {
                        ch.pipeline().addLast("stringEncoder", new StringEncoder(BufType.BYTE, CharsetUtil.UTF_8));
                    }
                });


        Channel peerChannel = b2.connect(remotePeerAddr).channel();
        peerChannel.write("42");     // Line 168
