【问题描述】：
我们正在尝试将 Tomcat 版本从 7.0.73 升级到更新的版本。在任何更高版本上，除了我们的“DBPrism Servlet Engine”之外，一切都运行良好。它部署没有任何问题，但是在运行测试时它会在 C-Prompt 中引发以下异常：

我查看了来自不同站点的多个帖子无济于事， 任何帮助将不胜感激
当前设置：带有最新 JDK - 1.8_144 的 Windows 10

感谢您的快速回复，不幸的是，划线帖子所指的系统是 Centos，如果我没有正确阅读，则指的是某种节点问题。他们中提到的帖子也归结为他们只是从 JDK 1.5 - 1.6 更新，我使用的是 JDK 1.8_144（可用的最新版本）

尝试更新版本的tomcat：tomcat.apache.org/download-80.cgi#8.0.46
-
如前所述，任何超过 7.0.73 的版本都会导致此问题。我已经尝试过直到并包括 tomcat 9 的所有版本。我能够找到的曾经的显着区别是所有较新的版本都包含一个“tomcat-util-scan.jar”，其中包含导致异常的类，这个类不是 7.0.73 库的一部分。
