I've got a question for everybody who's interested

I wanted to put a Java annotation which can only be targeted to `ElementType.TYPE` and `ElementType.FIELD` on the field in a Kotlin interface.
My annotation is set up like this in java:
```
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.FIELD})
public @interface MyAnnoation {
}
```

To only put `@MyAnnotation` on the field within the interface and not on get/set functions, I thus use the annotation use-site target (as described in <https://kotlinlang.org/docs/reference/annotations.html>) to set the annotation like this:
```
interface SomeInterface {
  @field:MyAnnotation val fieldX: TypeX
  val fieldY: TypeY
}
```

thinking this should work.
I however still get the compile exception: `Error:(18, 5) Kotlin: This annotation is not applicable to target 'member property without backing field or delegate' and use site target '@field'`

What's your guess, am I doing something wrong in my annotation or something in the way I try to set the annotation in the interface?
