Using validate(this) in init occurs error when it comes to open / abstract class

[JayAhn2]

Expected Behavior

Probably this report is due to my lack of proficiency in Kotlin. I want to validate values of a constructor in abstract or open class. If there is no way to achieve it as below. Please guide me how to do the same thing.

abstract class Quantity(open val value: Int) : BaseValueObject() {
    init {
        validate(this) {
            validate(Quantity::value).hasDigits()
        }
    }
}

Actual Behavior

Steps to Reproduce the Problem

1. Write abstract class as above

Example Code or Link to a Project

As above

Environment

• Valiktor version: 0.12.0
• JDK/JRE version: Open JDK 11
• Platform/OS: Mac

Yeah, logical here. Reason given here : https://stackoverflow.com/questions/9851813/java-leaking-this-in-constructor/9851843#9851843. Nothing valiktor could correct.

One suggestion, maybe : write a method instead, for example executeValidation(), and call this method from constructor or whatever in the child classes. This is the approach I elected to follow.
