Eclipse和Tomcat 8.0.35应用程序错误：非法访问：此Web应用程序实例已被停止

我正在64台计算机上的32位Eclipse EE Oxygen中运行Java应用程序，因为该程序将在以后转移到32位计算机上。该应用程序已连接到通过Wampserver安装的mysql，而我在该应用程序中使用的服务器是Apache Tomcat 8.0.35。当我在Eclispe的“运行方式>在服务器上运行”中运行应用程序时。我在“控制台”中收到以下错误消息：

 Illegal access: this web application instance has been stopped already. Could not load []. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.
java.lang.IllegalStateException: Illegal access: this web application instance has been stopped already. Could not load []. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

我该如何调试？
