Having had a look at code:

    public Future<WebSocket> websocket(String uri, String protocol, final WebSocketConnectCallback callback) {
        final AsyncHttpGet get = new AsyncHttpGet(uri.replace("ws://", "http://").replace("wss://", "https://"));
        return websocket(get, protocol, callback);
    }

The sample code in README use (String)null for protocol, is it ok?

Hi, i after checked the code, i found i didn't config the server side .websocket() method's regex arg and it occasionally doesn't match with client setting, after changed to "/*" it worked now.

        httpServer.websocket("/*", this);
        httpServer.listen(AsyncServer.getDefault(), tcpListenPort);
