Javax Validation Custom enum constrains in Kotlin

I'm trying to create a custom annotation and validator to use in conjunction with the javax validation Api and I'm having trouble access the values of an enum.

The objective of the annotation and the validator is validate if an input data is present within the enum values.

This is the annotation class

import javax.validation.Constraint
import javax.validation.Payload
import kotlin.reflect.KClass

@kotlin.annotation.Target(
    AnnotationTarget.FIELD,
)
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
@MustBeDocumented
@Constraint(validatedBy = [ValueOfEnumValidator::class])
annotation class ValueOfEnum(
    val enumClass: KClass<Enum<*>>,
    val message: String ="",
    val groups: Array<KClass<*>> = [],
    val payload: Array<KClass<out Payload>> = []
)

This is the validator implementation

import javax.validation.ConstraintValidator
import javax.validation.ConstraintValidatorContext

class ValueOfEnumValidator: ConstraintValidator<ValueOfEnum, CharSequence> {
    private val acceptedValues: MutableList<String> = mutableListOf()

    override fun initialize(constraintAnnotation: ValueOfEnum) {
        super.initialize(constraintAnnotation)

        acceptedValues.addAll(constraintAnnotation.enumClass.java
            .enumConstants
            .map {it.name}
        )
    }

    override fun isValid(value: CharSequence?, context: ConstraintValidatorContext): Boolean {
        return if (value == null) {
            true
        } else acceptedValues.contains(value.toString())

    }
}

I'm aiming to use annotation like this:

@field:ValueOfEnum(enumClass = SortDirectionEnum::class, message = "{variants.sorted.sort.direction.not.valid}")
    var sortDirection:String?=

But my IDE is reporting me the following error in the enumClass parameter

Type mismatch.
Required:KClass<Enum<*>>
Found:KClass<SortDirectionEnum>

How can I make the annotation generic enough to support different enums, and fix this issue ?
