Error is

I have this same problem with a new build I'm creating so I went to the document

I've had the same problem using OpenClover within a new ant build script, so to prove the problem wasn't with my script, I downloaded the latest OpenClover quick tutorial and built it using their maven script, same error (details above)
I heard back from OpenClover, apparently JDK17 is not supported. Still having troubles with jdk 1.8/1.9 (supported versions) and will update when I solve that.
