e_Child2.log

17:40:10.451 DEBUG [main] Parent - beforeClass()
17:40:10.453 DEBUG [main] Child2 - beforeClass2()

17:40:10.455 DEBUG [main] Parent - afterClass()

However, if we make Parent#beforeClass final like it should be, Child1 results in a compile error and the shadowing is avoided.

Since JUnit4 is annotation driven and not subclass driven, many methods can be annotated with @BeforeClass and will be executed in what appears to be parent to child order, however the order is undefined within the same class.
