我最近在WebSphere上部署应用程序时看到了这种情况。

当我在Tomcat上部署相同的WAR时，它是有效的。我使用的是JDK 1.7.80。其他人看到了吗？如果是，解决方法是什么？
提前谢谢。
module-info文件是在Java 9中新引入的。字节码扫描库(如ASM(需要更新才能理解新的module-info类文件，否则它们将遇到此异常。由于您在Java 7上运行，module-info.class文件没有任何作用(除了会导致ASM崩溃(。
您的选择似乎是：
- 将ASM更新到支持Java 9的版本，即ASM 6.0或更新版本
- 不要在应用程序中打包包含
module-info.class的库，例如stax-ex-1.8.jar - 从库(如
stax-ex-1.8.jar(中删除module-info.class文件，这样像ASM这样的字节码扫描工具在看到它们时就不会爆炸
