The current dir of the tomcat is /var/lib/tomcat8. This directory belongs to root and the tomcat user has no write permission.

I would prefer to have a fallback for this situation, eg. initializing log4j with a simple console appender. So the webapp could startup and the log will be catched by tomcat.
