[xwiki-users] java.lang.RuntimeException: Component manager has not been initialized before lookup

Hi, starting a few days ago, our XWiki application isn't running anymore. After restarting Tomcat, the following Stacktrace is shown. The XWiki version is 5.2.1. The logfiles mostly also show this stacktrace. Any help is welcome, thank you in advance.
