想用netty做websocket通信，启动方法为WebSocketServer.run(); 但是在nutzwk的Setup的init方法里面执行WebSocketServer.run()时，websocket服务能启动，也能正常与客户端通信，但是nutzwk启动不了，没有报错，不知道什么原因。

public static void run(){
        int port=8888;
        final WebSocketServer endpoint = new WebSocketServer();
        ChannelFuture future = endpoint.start(new InetSocketAddress(port));
        Runtime.getRuntime().addShutdownHook(new Thread() {
            @Override
            public void run() {
                endpoint.destroy();
            }
        });
        future.channel().closeFuture().syncUninterruptibly();
    }
