Thank you@derrabus.

shouldn't this also skip enums ?

Enums don't cause an issue as far as I can tell. Shall I add one to the fixtures just in case?

#48177

The fact that they don't have an issue is probably because the AnnotationClassLoader for the routing does not validate them (and so tries to load routes defined on them but it is unlikely to find some)

Yes. Not sure what happens though if someone tried to addRoute attributes to a enum method. 🙈

Probably a WTF error when trying to instantiate the controller (unless that part takes care of giving a better error message). However, I'm fine with failing for such case, as there is no valid reason for that (while a route in an abstract class might make sense in some cases where you have a child class belong loaded as well)
