Kotlin: Reified generics don't seem to work correctly for hash / equals comparison

Question

I have a card from KClassto Int. Then I have a function that is of type reified generic. Then I expected the following situation to give me IntrelatedBoolean::class

val kclassToInt = mapOf(Boolean::class to 1, Byte::class to 1, Short::class to 2)

inline fun <reified T> myExpectations() =
        assertEquals(1, kclassToInt.getRaw(T::class), "Why doesn't it work? :'(")

Welcome Why doesn't it work? :'(. Expected <1>, actual <null>.from calling him like myExpectations<Boolean>().

Then I tried to use .javaoff, so I used Java Class, not Kotlin KClass.

val classToInt = mapOf(Boolean::class.java to 1, Byte::class.java to 1, Short::class.java to 2)

inline fun <reified T : Any> anotherExpectation() =
        assertEquals(1, classToInt.getRaw(T::class.java))

This time I was again met with a statement error: java.lang.AssertionError: Expected <1>, actual <null>.

Finally, I tried using .javaClass, not .java:

val javaClassToInt = mapOf(Boolean::class.javaClass to 1, Byte::class.javaClass to 1, Short::class.javaClass to 2)

inline fun <reified T> pleaseWork() =
        assertEquals(1, javaClassToInt.getRaw(T::class.javaClass))

This time it was really strange. I was greeted as follows: java.lang.AssertionError: Expected <1>, actual <2>.Everyone seems .javaClassto relate to KClassImpl.

, , , .qualifiedName:

val qnToInt = mapOf(Boolean::class.qualifiedName to 1, Byte::class.qualifiedName to 1, Short::class.qualifiedName to 2)

inline fun <reified T> iKnowItWorks() =
        assertEquals(1, qnToInt.getRaw(T::class.qualifiedName))

Answer 1

, KClass (Java int, Integer). reified - KClass boxed (Integer), Reated Kotlin JVM?

KClass , , .

Answer 2

- println(type.javaClass), , , class kotlin.reflect.jvm.internal.KClassImpl, KClass.

type.javaClass ? javaClass - , Java- , . :

val <T : Any> T.javaClass: Class<T>

type - KClass<T>, type.javaClass result type - Class<KClass<T>>. , KClass. type KClassImpl , type.javaClass Class, kotlin.reflect.jvm.internal.KClassImpl.

, . , println(type). Java Class, KClass, , java: type.java. java:

val <T : Any> KClass<T>.java: Class<T>

, type KClass<T>, type.java Class<T>.
