So, I think this might be a trivial problem but am currently at a loss.
I created a vanilla Tomcat server on Ubuntu (tomcat-10.0.4).
It is configured to run on port 80 and I can see the Tomcat Manager fine.
Java has been installed
apt install default-jdk -y
Tomcat runs under its own user (tomcat) with full rights to its installation folder (/opt/tomcat)
chown tomcat: -R /opt/tomcat/
Magnolia was downloaded (magnolia-dx-core-demo-webapp-6.2.6.war)
The war file was renamed to magnoliaAuthor.war and the tomcat user made the owner of the file.
When moved to the webapps folder the war file is automatically extracted.
The ls -li command yields:
1283171 drwxr-x--- 6 tomcat tomcat 4096 Mar 29 15:12 magnoliaAuthor
256320 -rw-r----- 1 tomcat tomcat 486185464 Jan 27 17:37 magnoliaAuthor.war
So far so good. But in the Tomcat Web Application Manager I see the application is not running. I click Start and the application fails to start with only the following message:
FAIL - Application at context path [/magnoliaAuthor] could not be started
The logs are not helpful.

With the above information I don't see anything to point me in the right direction.
As pointed out in the comment, Magnolia is currently not compatible with Jakarta EE 9. You can follow progress on that issue at MAGNOLIA-8041
