  In Ubuntu 20.04, with `tomcat9-9.0.31-1ubuntu0.1` (latest) package, `logrotated` is not able to write to `/var/log/tomcat/catalina.out`
  This could be fixed in a newer package but was not backported:
  https://bugs.launchpad.net/ubuntu/+source/tomcat9/+bug/1861881
  
  In Ubuntu 22.04, with `tomcat9-9.0.58-1` (latest)  package, `logrotated`
  is not able to rotate `/var/log/tomcat/catalina.out`
  
  Because the `catalina.out` is created with `syslog:adm` ownerships.
  `syslog` user does not have enough permissions to change this.
  
  This causes following error:
  
  rsyslogd: error during config processing: omfile: chown for file
  '/var/log/tomcat9/catalina.out' failed: Operation not permitted
  [v8.2112.0 try https://www.rsyslog.com/e/2207 ]
  
  At the same time, the  `/etc/logrotate.d/tomcat9` has `su tomcat adm`
  directive. Therefore the `logrotated` is not able to truncate the
  `/var/log/tomcat/catalina.out`
  
  This causes logrotate to copy the contents of `/var/log/tomcat/catalina.out` to as if it would be rotated. As `catalina.out` is never truncated, each rotated file ends up having the contents of `catalina.out` from the beginning of the tomcat installation. This causes the log sizes to keep increasing as no actual log rotation is being done.
