Description
There is a change in behavior in JDK 24 where an error case throws NoClassDefFoundError rather than a ServiceConfigurationError with the NCFE as cause, see bug report here:

Comments
I have changes to restore the old behavior, mulling over whether to address the wider issue at the same time or not.
