Question

我正在调查以下带有以下堆栈跟踪的java.lang.VerifyError.Exception：

Exception in thread "Thread-2" java.lang.VerifyError: class org.eclipse.jetty.websocket.common.io.AbstractWebSocketConnection overrides final method toString.()Ljava/lang/String;

我尝试使用相同版本的jett-server版本和spark，但我得到了相同的结果。任何想看的地方都会有所帮助。

Answer 1

处理你的websocket代码的库比你的服务器旧。

运行$ mvn dependency:tree，您将看到混合版本的来源。
