Describe the bug
Thank you for the additional Kotlin support in 4.2! I'm attempting to upgrade from 4.1, but with 4.2 I'm hitting a ClassCastException for a class that uses interface delegation.
Steps to reproduce
Diff/reproducer here: sdkotlin/sd-kotlin-talks@bcd4c59. The test passes before the changes.
