After some research, I found a JIRA issue (ALFCOM-1362) that exposes a problem similar to mine. The issue was reported more than a year ago and is still open so I guess there's no easy answer.

So I moved log4j-1.2.15.jar from tomcat/webapps/alfresco/WEB-INF/lib to tomcat/lib. Now I still have the unexpected server shutdown, but the message has changed:

log4j:WARN No appenders could be found for logger (org.alfresco.repo.shutdown.Sh

log4j:WARN Please initialize the log4j system properly.
