I just installed the latest Tomcat 9 from <https://tomcat.apache.org> on
two servers running Ubuntu 16.04 and OpenJDK 8 yesterday and it worked
fine to just checkout the source, run mvn package and copy the resulting
files into the Tomcat's webapp directory.

Are you using a stock Tomcat from apache.org or the Debian/Ubuntu version?

That's digilib's message that it doesn't have the right codec. I was
thinking more about Tomcat's warning about its "leak prevention".

Hmm, that is really strange.

Can you try to run digilib in Maven with "mvn jetty:run-exploded
--projects webapp" as documented in the Readme on
<https://github.com/robcast/digilib>?

Best
