Data class nested inside interface causes NoSuchElementException at SekretClassBuilder.kt:92

[aSemy]

This is a really specific issue! It took a while to track down.

When a data class is defined inside an interface, it causes an exception

This is the most simple example I could create. Any changes to Product or ProductData fix the issue.

@JvmInline
value class ProductId(  val value: String)

interface Product {
    val id: ProductId

    data class ProductData(override val id: ProductId) : Product
}

fun main() {
    val product = Product.ProductData(id = ProductId("asd"))

    println(product)
}
