我可以确认应用程序的某些部分运行良好，例如一些安静的 json 端点（它们确实响应正确的 json 数据） 但是任何 JSP 页面渲染都死了......错误日志看起来像这样：

所以我认为这与 java 8 env 问题有关？但是在heroku上，我相信tomcat的版本默认是9 https://devcenter.heroku.com/changelog-items/1724 但我不知道如何使用 heroku cli 实际检查我的 tomcat 版本，有人知道吗？
或者看起来像heroku tomcat问题？如果是这样，我应该使用哪个版本的 tomcat？ 请指教 谢谢
解决方法
能否请您尝试将 web-runner 依赖项升级到 9.0.27.1？目前设置为，
