Comment 1 for bug 1861881

In previous versions of tomcat (and ubuntu) we see the permissions to this directory as follows:

/var/log/tomcat7# ls -lah
drwxr-x--- 2 tomcat7 adm 156K Feb 4 00:00 .
drwxrwxr-x 22 root syslog 4.0K Feb 4 06:51 ..
-rw-r--r-- 1 tomcat7 adm 0 Feb 2 06:54 catalina.out

/var/log/tomcat8# ls -lah
drwxr-x--- 2 tomcat8 adm 4.0K Feb 4 06:25 .
drwxrwxr-x 16 root syslog 4.0K Feb 4 06:25 ..
-rw-r--r-- 1 tomcat8 adm 0 Feb 2 06:25 catalina.out

Where as currently with tomcat9 it has changed (the adm group is missing from the directory and from the catalina.out file)
ls -lah /var/log/tomcat9/
total 792K
drwxr-x--- 2 tomcat tomcat 4.0K Feb 4 14:28 .
drwxrwxr-x 15 root syslog 4.0K Feb 4 06:25 ..
-rw-rwxr-- 1 tomcat tomcat 0 Feb 2 06:25 catalina.out
