Kotlin Reflection with Proguard - Incomplete hierarchy for class

I'm running into an issue at runtime when using Proguard with Kotlin reflection. Basically, when I am calling KClass.declaredMemberProperties, I get:

Incomplete hierarchy for class FieldBoundObject, unresolved classes [com.example.test.classes.DisposableObject]
kotlin.reflect.jvm.internal.components.RuntimeErrorReporter.reportIncompleteHierarchy

Here is the relevant stacktrace:

Here is the relevant call in Fieldbinder.kt:

class FieldBinder(receiver: Any) {

    private fun bindFields(receiver: Any, classToCheck: Class<*>) {
        for (property in classToCheck.kotlin.declaredMemberProperties) {
            //...
        }
    }

    // ...
}

Here is the signature for the "missing" class DisposableObject

package com.example.test.classes

open class DisposableObject : ScopeProvider, Dispose {

    //...
}

I think it has something to do with name obfuscation. I've tried using @Keep on the actual class itself, as well as using -keep class on the class itself in my Proguard file. However, what DOES solve the problem is keeping names in Proguard:

-dontobfuscate

or

-keepnames class com.example.test.classes.DisposableObject

Is there an issue with name obfuscation and Kotlin reflection? I'm not having the same issues with Java reflection. Or is there a better way to solve this problem? Thanks!
