OnMessage(WebSocket)不工作在Glassfish, Java 8

我在运行Java EE应用程序时遇到了麻烦。我为服务器edpoint设置了以下代码:

import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.enterprise.context.ApplicationScoped;
import javax.websocket.*;
import javax.websocket.server.ServerEndpoint;

@ApplicationScoped
@ServerEndpoint(
        value = "/model" 
)
public class ModelWebSocket {

    private final ModelHandle model = new ModelHandle();   
    @OnOpen
    public void onOpen(Session session) throws IOException {
    }
    @OnError
    public void onError(Throwable error) {
        /// put model back to pool, log erros
    }

    // This code never calls,
    @OnMessage
    public void onMessage(String message, Session session) {
        //TODO: Add decoders/encoders to annotations
        try {       
            ModelInputData inputData = new ModelInputDataDecoder().decode(message);         
            double input = inputData.getInput();
            double timespan = inputData.getTimespan();
            model.setInput(input);
            ModelProcessData process = model.getOuptput(timespan);
            try {
                session.getBasicRemote().sendText(
                        new ModelProcessDataEncoder().encode(process)
                );
            } catch (IOException | EncodeException ex) {
                Logger.getLogger(ModelWebSocket.class.getName()).log(Level.SEVERE, null, ex);
            }
        } catch (DecodeException ex) {
            Logger.getLogger(ModelWebSocket.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}
And the following stub for a client stub in javascript:
<!DOCTYPE html>
<!--
This is a test
-->
<html>
    <head>
        <title>Test</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
    </head>
    <body>
         <!-- insert the main script here -->
        <script type ="text/javascript">
            //copied from https://learn.javascript.ru/websockets
            var socket = new WebSocket(
                    "ws://localhost:8080/SimulatorWeb/model"
                    );
            socket.onopen = function () {
                alert("Connection OK");
            };
            socket.onclose = function (event) {
                if (event.wasClean) {
                    alert('Connection closed');
                } else {
                    alert('Connection interrupted'); // например, "убит" процесс сервера
                }
                alert('Code: ' + event.code + ' redason: ' + event.reason);
            };
            socket.onmessage = function (event) {
                alert("Data accepted " + event.data);
            };
            socket.onerror = function (error) {
                alert("Error " + error.message);
            };

            function send(){ 
              socket.send("dummy");
            }
        </script>
        <button type="button" onclick="send();" >Send</button>
    </body>
</html>

客户端似乎发送消息，但OnMessage从未被截获。当我启动Glassfish 4.1.1时，我有以下警告:

WARN: WELD-000411: Observer method [backkedannotatedmethod] privateorg.glassfish.jersey.ext.cdi1x.internal.CdiComponentProvider.processAnnotatedType (@ObservesProcessAnnotatedType)接收所有注释的事件类型。考虑使用@WithAnnotations或a来限制事件带边界的泛型类型。警告:WELD-000411:观察者方法(BackedAnnotatedMethod)公共org.glassfish.jms.injection.JMSCDIExtension.processAnnotatedType (@ObservesProcessAnnotatedType)接收所有注释的事件类型。考虑使用@WithAnnotations或a来限制事件带边界的泛型类型。警告:WELD-000411:观察者方法(BackedAnnotatedMethod)org.glassfish.sse.impl.ServerSentEventCdiExtension.processAnnotatedType (@ObservesProcessAnnotatedType, BeanManager)接收所有事件注释类型。考虑使用@WithAnnotations限制事件

我花了很多时间调试，但我仍然无法找到问题…我使用Java 8 SDK和NetBeans IDE。

(在代码中，我没有使用解码器/编码器，因为我认为它们是问题并从ServerEnpoint中删除了它们)

我不知道Glassfish的问题是什么…我切换到Tomcat，并手动添加到WEB_INF/lib所有我需要的外部库(javax;Json)。Tomcat似乎没有给原始代码任何警告，一切都工作得很好。
