Update: I think this is a test bug.

@Maran23 Can you confirm a theory I have? We have a situation where an abstract base class of a test has a static `tearDownOnce` method, annotated with `@AfterAll`. A concrete test class extends the base class and attempts to "override" the static method in the base calss with an `@AfterAll` annotation on a static method of the same name in the subclass. My suspicion is that this used to accidentally work by hiding the method in the parent class in JUnit 5.8 and no longer does.
