commons-daemon is a third party dependency, so this compilation issue is possible ... It seems we haven't double checked this one basically. All the classes that are compiled from the Tomcat repository are release targeted at 1.7, and some important dependencies are verified (like JDT). BTW, Tomcat 8.5 is now EOL, you should plan to upgrade to Tomcat 9.0.
