I’ve just upgraded from 14.2.1 to 14.6; everything went smooth but I discovered (didn’t notice it before), that Tomcat doesn’t stop even after three minutes.
XWiki runs inside Apache Tomcat/9.0.62, JVM 11.0.16+8-post-Ubuntu-0ubuntu120.04; installed manually from the WAR distribution; on a Ubuntu 20.04 virtualized box.

OK, they’re warnings, but is there anything I should do or check?
As a side note, I think it shouldn’t make any difference, however despite what’s suggested in the docs, I put the MySQL driver in Tomcat common /lib directory (this TC is only used for XWiki anyway).
I’ve run journalctl -r -x -u tomcat9 and this is the output:
