Kotlin immutable list causes exception

[elifarley]

If I try to read an Any as a Kotlin data class that contains an immutable list, I get an error on ReflectionCollectionDecoder.decode_ line 44: col.clear()

Example data class that causes the error: data class Example(val problem: listOf<Int>())

See #55

I have no experience of kotlin. Any one can help on this?

listOf<Whatever>() returns an immutable implementation of empty list, which is like Java's emptyList().
