Tomcat version: 10.0.27 (unzipped, chmod 770 on catalina.sh before
cli: catalina.sh run)
java version: openjdk version "9-internal"

First error in logs:

java.lang.ClassNotFoundException: java.lang.ModuleLayer
You appear to have a broken JRE. That class should always be present in
Java 9 onwards.

Hi Everyone;
I've had a few requests to refurbish some old 32 bit dell towers.
So, I'm throwing ubuntu on them and bringing up a MySQL->DB2DOM->Tomcat
stack.
Unfortunately, Tomcat doesn't want to start with openjdk 9 that is
packaged with 32 bit ubuntu.
Tomcat works happily with 32-bit and 64-bit Java.
Can someone give me a pointer to what works best?
Perhaps if you told us what Tomcat version you were using and showed us
what the error message was we'd be able to provide slightly more advice
than "You are doing something wrong. Don't do that".

Also, any heads up about missing libs or other nuances would also be
appreciated (jax mods were most painful).
