Your is wrong?
It looks like it does not specify where the messages from
"org.apache.catalina.startup.Catalina" log category should be written.

> I also deleted the from $CATALINA_BASE/conf

One should not delete the file itself, but only its contents, leaving
an empty file.

> Can anyone please tell me why this warning is occurring when I replace tomcat-juli.jar?
 Any help is greatly appreciated.
