Client Kotlin exception with list of enum as input type

[robp94]

Using the client in kotlin with a list of enums as input types results in a RuntimeException.

java.lang.RuntimeException: unsupported reflection type class sun.reflect.generics.reflectiveObjects.WildcardTypeImpl

This only happens if the client interface is in kotlin, if it is in java it works.

java

    @Mutation
    List<E> list(@NonNull List<@NonNull E> es);

kotlin

    @Mutation
    fun list(es: @NonNull List<@NonNull E>): List<E>

Running the following query results in the exception

query d {startList}

I have no idea what Kotlin is producing here. Looks like it's using internal classes in sun.reflect.generics.reflectiveObjects. Maybe you can investigate and provide a PR?
