I had the same error.I was using tomcat 8 with java 8 .I upgraded to tomcat 9 and the problem was solved.Guess it has something to do with some new feature in java 8
我有同样的错误。我在 java 8 中使用了 tomcat 8。我升级到 tomcat 9 并且问题解决了。猜测它与 java 8 中的一些新功能有关

Which jdk version you are using? I tried with jdk version after 1.8.0_92 and issue got resolved for me. Before that my jar artifacts were not able to build due to NoClassDefFoundError. Though compilation shown valid class existence.
你用的是哪个jdk版本？我在 1.8.0_92 之后尝试使用 jdk 版本，问题已为我解决。在此之前，由于 NoClassDefFoundError，我的 jar 工件无法构建。虽然编译显示有效的类存在。
