Java，Websockets，tyrus服务器：握手错误

Question

ServerApp：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import org.glassfish.tyrus.server.Server;

public class ServerApp {

    public static void main(final String[] args) {
        ServerApp server = new ServerApp();
        server.runServer();
    }

    public void runServer() {
        Server server = new Server("localhost", 8025, "/websocket", null, ServerEndPoint.class);

        try {
            server.start();
            BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Please press a key to stop the server.");
            reader.readLine();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
        server.stop();
        }
    }
}

ServerEndPoint：

import java.io.IOException;
import java.util.logging.Logger;
import javax.websocket.CloseReason;
import javax.websocket.CloseReason.CloseCodes;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint(value = "/game")
public class ServerEndPoint {

    private final Logger logger = Logger.getLogger(this.getClass().getName());

    @OnOpen
    public void onOpen(Session session) {
        System.out.println("Connected ... " + session.getId());

    }

    @OnMessage
    public String onMessage(String message, Session session) {
        System.out.println("onMessage: "+message);
        switch (message) {
        case "quit":
            try {
                session.close(new CloseReason(CloseCodes.NORMAL_CLOSURE, "Game ended"));
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
            break;
        }
        return message;
    }

    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        System.out.println("onClose: "+String.format("Session %s closed because of %s", session.getId(), closeReason));
        logger.info(String.format("Session %s closed because of %s", session.getId(), closeReason));
    }
}

这很有效，服务器启动并等待客户端。

ClientApp：

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.util.concurrent.CountDownLatch;
import javax.websocket.ClientEndpoint;
import javax.websocket.DeploymentException;
import org.glassfish.tyrus.client.ClientManager;

@ClientEndpoint
public class ClientApp {
    public static CountDownLatch latch;
    public static void main(String[] args) throws IOException {
        latch = new CountDownLatch(1);

        ClientManager client = ClientManager.createClient();
        try {
            client.connectToServer(ClientApp.class, new URI("ws://localhost:8025/websockets/game"));
            latch.await();

        } catch (DeploymentException | URISyntaxException | InterruptedException e) {
            throw new RuntimeException(e);
        }
    }
}

ClientEndPoint：

import java.util.logging.Logger;
import javax.websocket.ClientEndpoint;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;

@ClientEndpoint
public class ClientEndPoint {

    private final Logger logger = Logger.getLogger(this.getClass().getName());

    @OnOpen
    public void onOpen(Session session) {
        // same as above
        System.out.println("onOpen");
    }

    @OnMessage
    public String onMessage(String message, Session session) {
        // same as above
        System.out.println("onMessage");
        return "";
    }

    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        System.out.println("onClose");
        logger.info(String.format("Session %s close because of %s", session.getId(), closeReason));
        ClientApp.latch.countDown();
    }
}

当我尝试连接时：Exception in thread "main" java.lang.RuntimeException: javax.websocket.DeploymentException: Handshake error.

我不知道是什么造成的。
