我正在将Tomcat 7中的webapp移植到另一台使用Tomcat 7但使用Java 8的服务器上.

Tomcat成功启动但在日志中catalina.out我得到:

可能是什么问题呢？

我试图升级到Java 8时开始我们的tomcat7服务器,使用Java 7编译.war文件,我得到下面的神秘错误.

我应该期待这个吗？这篇文章说tomcat 7应该可以使用1.6及更高版本.我不知道Tomcat是应该责备还是.war.切换出我得到的不同Java版本:

• 安装JDK 7.45 - 工作(用于编译.war的相同版本)
• 安装JDK 7.55 - 失败如下
• 安装JDK 8.05 - 失败如下

是tomcat还是.war？
