Estou usando a API do cliente do Jetty 8.1.1 Websocket.
Eu preciso atualizar os cabeçalhos com("Sec-WebSocket-Protocol", "xsCrossfire") e("Authorization", "Basic TLVWQMZqRr2hasYnZoI=")

WebSocketClientFactory factory = new WebSocketClientFactory();
factory.start();
client = factory.newWebSocketClient();
client.getCookies().put("Sec-WebSocket-Protocol", "xsCrossfire");
client.getCookies().put("Authorization", "Basic TLVWQMZqRr2hasYnZoI=");
Future<Connection> conn = client.open(uri, (WebSocket) this);
System.out.printf("Connecting to : %s%n", uri);

solicitação parece:

Host: iltlvl262:8000\r\n
Upgrade: websocket\r\n
Connection: Upgrade\r\n
Sec-WebSocket-Version: 13\r\n
Sec-WebSocket-Key: FHKTsICO2vqGCxXVwLkH4Q==\r\n
Cookie: Sec-WebSocket-Protocol=xsCrossfire\r\n
Cookie: Authorization="Basic TLVWQMZqRr2hasYnZoI="\r\n

pedido esperado:

Host: iltlvl262:8000\r\n
Upgrade: websocket\r\n
Connection: Upgrade\r\n
Sec-WebSocket-Version: 13\r\n
Sec-WebSocket-Key: FHKTsICO2vqGCxXVwLkH4Q==\r\n
Sec-WebSocket-Protocol: xsCrossfire\r\n
Authorization: "Basic TLVWQMZqRr2hasYnZoI="\r\n

Como faço para implementar o handshake na versão 8.1.1 corretamente?
