我刚从Java 7升级到Java 8，Tomcat 8里面跑的是一个app，貌似没问题，但是里面/var/log/tomcat8/catalina.out我发现了以下错误信息:

这些错误是在服务器启动完成后记录的，但没有再出现。
看起来不像典型的 Unsupported major.minor version 52.0，但我猜这可能与 Java 升级有关，有什么想法吗？
内部运行的唯一 WAR 是用 Java 7 编译的，但我想 Java 8 应该可以处理它。
环境细节:
- Apache Tomcat/8.0.14 (Debian)
- OpenJDK 1.8.0_121-8u121-b13-1~bpo8+1-b13
- Debian GNU/Linux 8.7(杰西)
最佳答案
我面临同样的上述问题，但在将 apache tomcate 的升级版本从 8.0.14 升级到 8.5.14 后，它对我来说已经解决了
希望对您有所帮助。
谢谢
