Hi Andy!

I've tried a few more builds today.

On my main Ubuntu 24.04 machine (same as before) where the 5.4.0 build 
always fails, I collected complete maven logs of the failed build. I 
will send them to you separately. I also looked for the first exception 
traceback (there are many) and it's included at the bottom of this message.

Got the logs.

It's hiding the real reason inside a java.lang.ExceptionInInitializerError
- the place moves around a bit but the first few are from 
RDFParserRegistry.init

java.lang.ExceptionInInitializerError

What I could do is make a branch, add some logging to catch any errors 
and log them.

I also tried installing maven 3.9.9 and using that for the build, but 
the result was the same as with 3.8.7: the ARQ tests failed with 
NoClassDefFoundError.

Then on another machine (VirtualBox VM with Ubuntu 24.04), I installed 
the exact same Java and Maven versions as on my main machine. The build 
succeeded!

I always remove my maven repository (rm -rf ~/.m2) before each build.

So it's not the specific Maven or Java version that causes the problem, 
but something else that I can't yet pinpoint.

A thought - are you using a maven mirror?
