I need to perform a static analysis of the program (use SootUp library, v.:1.2.0). I can’t retrieve the annotations of the class fields.

My custom annotation (Kotlin):

package annotation

@Target(AnnotationTarget.FIELD)
@Retention(AnnotationRetention.RUNTIME)
annotation class StateVar(val value: String = "")

My class with annotated field:

class TrafficLight {
    @field:StateVar("mode")
    private var mode: Int = 0
    ...
}

I need to retrieve this annotation:

...
val sootClass = view.getClass(classType).get()
sootClass.fields // <-- empty annotation list (pic below)

Could you explain to me how to access such annotations using the SootUp? What is my mistake?
