Ok this time it's a very different error which indeed looks more serious. But it still seems related to persistent storage of the session and in this case it seems to be trying to load a saved request (which is really not the kind of thing that make sense to store). For me your Tomcat is in a pretty weird state and try to load stuff that don't make much sense in the context of XWiki but I don't know anything about persistent storage. Seems to be to have something to clean somewhere and some option to disable (if it's still enabled).
Tomcat cannot find the class org.xwiki.container.servlet.filters.SavedRequestManager$SavedRequest which is supposed to be located in jar /usr/lib/xwiki/WEB-INF/lib/xwiki-platform-container-servlet-<version>.jar. You should probably check if you have this jar file and if tomcat is allowed to read it.
