Some context: If a user session has expired, Tomcat wants to show the error page. But the error page cannot be shown because it references /WEB-INF/templates/base.xhtml, which includes /WEB-INF/templates/includes/header/navigation.xhtml, which renders #{SessionClientController.currentSessionClientName}, that cannot be obtained because there is no user (due to the vanished session).
