As an FYI, the behavior change that exposed the bug in our test was a deliberate change in JUnit 5.11.

https://github.com/junit-team/junit5/issues/3553

Indeed it was the case that before 5.11, a static method annotated with `@BeforeAll` or `@AfterAll` in a subclass would hide the same named method in the superclass, and starting in 5.11, it no longer does.
