我试图使旧的Java 7 EE WebSocket应用程序：https://www.oracle.com/webfolder/technetwork/tutorials/obe/java/HomeWebsocket/WebsocketHome.html在Payara Server 5.184 #badassfish（build 89）中工作
但是，WebSocket（@ServerEndpoint）无法实例化。
Severe: Exception in thread "glassfish-web-async-thread-1" Severe:

通过启用CDI开发模式，我看到：
WARN: WELD-001703: Unable to determine the @Intercepted Bean<?> for
[UnbackedAnnotatedField] @Inject @Intercepted private
org.jboss.weld.probe.InvocationMonitor.interceptedBean WARN:

DeviceWebSocketServer是我的@ServerEndpoint类。有没有与CDI有关的错误？我能错过什么？
代码在这里：https://github.com/DanielMerchan/WebsocketHome如果有人想尝试一下。这在我以前使用Glassfish的旧Netbeans中工作（不记得版本）。
谢谢。
如果我保留Java EE 7，它就可以工作。升级到Java EE 8时不知道发生了什么。
