Question

我们将Struts2从v2.5.13升级到v2.5.17。实际上，在没有其他更改之后，Tomcat v7.0.61（运行应用程序的容器）将引发以下异常：

SEVERE: Unable to process Jar entry [module-info.class] from Jar [jar:file:/opt/apache-tomcat-2nd/webapps/portal/WEB-INF/lib/log4j-api-2.10.0.jar!/] for annotations

我尝试根据this answer将catalina.properties更改为将tomcat.util.scan.DefaultJarScanner.jarsToSkip下的log4j-api-2.10.0.jar包括在内，但是并没有解决问题。我知道这不会改变应用程序的行为，包括日志记录，但是我更喜欢使日志文件中没有非问题和其他虚假警报，以使异常发生时具有实际含义（又称为“不哭狼”））。

如何消除此异常？

升级Struts2后，Tomcat引发ClassFormatException
