RequestHeader annotation does not work if it's put on an interface [SPR-15023]

[spring-projects-issues]

Andrei Sfat opened SPR-15023 and commented

Basically, I have a controller which is an interface where I put every annotations on that interface and when I implement that interface, apparently RequestHeader is not picked up.
If I repeat myself and put the RequestHeader in the implementation, it will work fine.

Shouldn't this annotation work the same as the other annotations? I think I've tried almost all annotations and they are picked up correctly.

I've attached a example.

This looks a duplicate of the more general #15682. It's on our roadmap for 5.0.
