Right, the issue has been solved.
The library ended up on the classpath, because the module descriptor could not
be read (Classfile API will solve this in the future).
Plexus-java is the library responsible for this.
The latest version op plexus-java supports Java 23, and based on the
documentation of the maven-surefire-plugin it should be using the latest
version of plexus-java.
What I didn’t notice is that the maven-plugin *overview* says 3.5.0 is the
latest maven-surefire-plugin version, whereas the documentation was generated
for *3.5.1*.
So it was a mismatch in the documentation that confused me.
Sorry for the noise,
Robert

Subject: Re: ServiceLoader fails for Java 23 with preview enabled
Christian Stein mentioned that this is something to due with Surefire not
supporting JDK 23 class files, is that right?

Hi,
It seems there’s a change in the ServiceLoader, and it looks like regression to
me.
I’ve created a small project to reproduce it (I can provide it if wanted and
confirmed this is indeed a bug).
What it basically does is just:
ServiceLoader.load(Car.class).findFirst().orElseThrow();
This succeeds with OpenJDK 22 (with and without preview enabled flag)
It also succeeds with OpenJDK 23 without the preview flag.
However, when adding the preview flag I get:
java.util.NoSuchElementException: No value present
at java.base/java.util.Optional.orElseThrow(Optional.java:377)
at nl.sourcegrounds.serviceloader.tck.CarTest.<init>(CarTest.java:16)
Anyone who can already explain this with this small amount of information?
Thanks,
Robert Scholte
