无法为JSP编译类：无法解析类型java.util.Map $ Entry从所需的.class文件间接引用它

(adsbygoogle = window.adsbygoogle || []).push({}); 如何解决无法为JSP编译类：无法解析类型java.util.Map $ Entry从所需的.class文件间接引用它？

你必须使用支持JDK 8的最新版本的tomcat。

我可以确认apache-tomcat-7.0.35不支持JDK8，也可以确认apache-tomcat-7.0.50不支持JDK8。

解决方法

我无法获取tomcat7来编译jsps。直到运行示例servlet一切正常，并且服务已启动并正在运行。我正在运行oracle java 8。

谁能指出我正确的方向？

这是堆栈跟踪：

该代码看起来像这样，这是来自tomcat7的示例代码，所以我想这是正确的。
