Hi Andrew,
It looks like a 4.1->4.2 change - that's where log4j-api, and log4j-core
stop appearing in the war file. So not related the log4j chnages this
release.
I haven't found a change that caused this yet. I noticed they were
optional while clearing up yesterday yet still getting into the shaded
jars which looked odd, so did PR 1113.
It might be an order-dependent effect in the build or some maven upgrade
changed and had an effect on the war-plugin.
A fix should be to is to edit the war file (it's a zip file) and add the
jars into WEB-INF/lib/.
WEB-INF/lib/log4j-core-2.15.0.jar
WEB-INF/lib/log4j-api-2.15.0.jar
or add to the Tomcat server (untested).
I've added it to the PR:
https://github.com/apache/jena/pull/1131
----
Some nearby questions if I may:
Is the Tomcat installation running only Fuseki?
Would it be reasonable to distribute the war file via a link from the
download page or link in README?
The apache-jena-fuseki file is getting big because it has two copies of
Fuseki in it.

Hello,
I decided to upgrade our Fuseki 3.17.0 running on Tomcat 9 to the latest
version released yesterday (thank you, Andy, for your hard work and a late
night release!). I ran into the “java.lang.NoClassDefFoundError:
org/apache/logging/log4j/Logger” exception. The closest issue I found was
https://stackoverflow.com/questions/20909446/caused-by-java-lang-noclassdeffounderror-org-apache-log4j-logger
but I don’t think Fuseki WAR file has these problems.
I am able to start the newest Fuseki server in the standalone mode without
problems:

The Tomcat server is quite a vanilla tomcat9 package installation under Ubuntu
20.04 LTS. Do you have an idea where I should look at next? I checked out
https://jena.apache.org/documentation/fuseki2/fuseki-webapp.html#fuseki-with-tomcat9-and-systemd
and already have the systemd edits suggested. Thank you in advance!
