I'm trying use Koltin Poet to generate data classes for JPA. I'm stuck at trying to create a

val owners: MutableSet<MyObject> = mutableSetOf()

because

MutableSet::class

is

class kotlin.collections.Set

and not

class kotlin.collections.MutableSet

. Any idea why that is the case (or even better what I can do to fix this)?

MutableSet

and co don't exist at runtime.

Hmm. I looked at the source and both

Set

and

MutableSet

are interfaces. I "cheated" for now by using a literal String

Right, the kotlin source for them exists.

Ah, good to know. So seems there is no way around my cheating.
