Spring @Async annotation does not recognize executor parameter for methods from parent class in Kotlin.

Affects: Spring Boot 2.5.2

---

Kotlin code:

The following code does not respect "asyncFlatFeedExecutor" param of the @Async annotation when follow method is called on AsyncFlatFeedService bean. However, it is executed asynchronously, but on the default executor.

@Primary
@Service
@Async("asyncFlatFeedExecutor")
class AsyncFlatFeedService : DefaultFlatFeedService()

@Service
class DefaultFlatFeedService {
    override fun follow(follower: Long, following: Long) {
      // async logic is here
    }
}

But if we add override fun follow(follower: Long, following: Long) even w/o annotation to AsyncFlatFeedService, everything works fine.

I guess this DefaultFlatFeedService class extending nothing but overriding follow function is not complete, could you please provide a reproducer (full project attached or related repository URL) to allow us to have a deeper look?

@sdeleuze sorry for the typo, here is the correct version:

@Primary
@Service
@Async("asyncFlatFeedExecutor")
class AsyncFlatFeedService : DefaultFlatFeedService()


@Service
class DefaultFlatFeedService {
    fun follow(follower: Long, following: Long) {
      // async logic is here
    }
}
