Yes. As I said, when using System.err.println() instead log
log.trace(), I do get logging (to stderr).

I'm using bin/catalina.sh start to launch Tomcat on Macos. The 'ps'
command shows the following partial command-line:
[...]
- -Djava.util.logging.config.file=${CATALINA_BASE}/conf/logging.properties
- -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager [...]
The file ${CATALINA_BASE}/conf/logging.properties does indeed have the
changes below.

I did that in desparation after FINEST wasn't getting the job done.

So... what else should I check?
