Inner class creates failure in Kotlin

Question

This sample code cannot be compiled and an internal error is displayed.

open class TestClass { open inner class Back { open fun dd() { } } } class Manager: TestClass() { private val test = object : Back() { override fun dd() { } } } 

Cause:

Error creating null class constructors with implementation type

What does it mean?
