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，因为错误已得到修复。

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