After resolving other issues I had with an upgrade to Xwiki 16.10 I have noticed that tomcat fails to start on a fresh system boot, and needs to be manually restarted.
After a fresh boot, the journalctl log shows:
-- Boot ab9f9e756bef4aa7be96f7b3e9126e68 --
Jan 06 13:52:00 wiki.tuxdomain systemd[1]: Starting Apache Tomcat 9 Web Application Server...

Jan 06 13:52:00 wiki.tuxdomain systemd[1]: Failed to start Apache Tomcat 9 Web Application Server.
And the web page displays Bad Gateway Error 502.
If I restart the Tomcat9 service manually (systemctl restart tomcat9), it works as expected. This is the journbalctol log after a tomcat service restart:
