Hello,

I think we can close this with your equivalent of "not our issue".

The VerifyError is a strange one, which I fixed by changing FooValidator to no longer extend FooValidatorNoImplementsConstraintValidator and basically copy/pasting the formerly inherited methods into FooValidator. At that point, the VerifyError goes away, and maven test runs to completion sucessfully.

In fact, I never did use maven test, I was always using IntelliJ's "Run All Tests". When you do this, it produces the stacktrace in the description of this issue. So it's very likely an issue with IntelliJ's test runner

Apologies for the noise.
