问题描述

根据catalina.out安装Oracle Java 8并将tomcat7指向java8会产生以下错误：

Installing Oracle Java 8 and pointing tomcat7 to java8 produced the following error as per catalina.out:

我正在使用： -
Tomcat版本：7.0.26&
Oracle Java：8

I'm using:--Tomcat version: 7.0.26 &Oracle Java: 8

我看过很多帖子建议将Tomcat升级到7.0.53或更高版本。但有没有解决方法来解决问题而不升级Tomcat？

I've seen lot of posts suggesting to upgrade Tomcat to 7.0.53 or higher. But is there any workaround to resolve the issue without upgrading Tomcat?

推荐答案

将Tomcat升级到至少7.0.30。 >
它应该有效，因为已得到修复。

Upgrade your Tomcat to at least 7.0.30.
It should work because this bug was fixed.

这篇关于Tomcat 7和Java 8兼容性问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
