Log4j: Error logmananger. repositoryselector was null likely due to error in class reloading, using noploggerrepository.

The reason is that I changed the struts2-core-2.1.6.jar and struts2-spring-plugin-2.1.6.jar to version 2.3.8. I wanted to replace it with a new version. I couldn't think of this error.
