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)?

[karelpeeters]

MutableSet and co don't exist at runtime.

[nkiesel]

Hmm. I looked at the source and both Set and MutableSet are interfaces. I "cheated" for now by using a literal String

[karelpeeters]

Right, the kotlin source for them exists.

[karelpeeters]

But ArrayList and other JVM implementations of lists can't know about the interface, so the kotlin compiler has to cheat.

[nkiesel]

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