To enable the mitigation for Apache Tomcat, set `JAVA_OPTS=-Dlog4j2.formatMsgNoLookups=true`

For instance, when starting with systemd, add `Environment=JAVA_OPTS=-Dlog4j2.formatMsgNoLookups=true` to your service file.

You should find `Command line argument: -Dlog4j2.formatMsgNoLookups=true` in catalina.out
