Cannot transform *class as its containing application archive could not be found

I have created an MCVE where I have the classic greeting resource and I’ve added a Utility class (private constructor w. one static method).

When using jacoco-extension the tests run just fine, but when adding quarkus-smallrye-openapi, dependency, I get these warnings when running tests:

Are the warnings valid (and thus I am misusing something)? ~Is such a utility class to be avoided in CDI?~
In our project, the warning is actually generated in non utility classes, as well.

To Reproduce

Steps to reproduce the behavior:
