Upgraded to jackson 2.12.x and it's been failing my builds in Kotlin 1.3.x which seemingly for a method not being available. I'm unable to figure out if this is breaking change coming from Jackson.

 Caused by: java.lang.NoSuchMethodError: kotlin.reflect.KClass.getSealedSubclasses()Ljava/util/List;

Looks like some things have been depreciated in the upgrade.

You need to look at the upgrade notes, because this method doesn't exist anymore getSealedSubclasses()

You might find the answer here: https://github.com/FasterXML/jackson/wiki/Jackson-Releases

If you cant find it here, you will need to create a bug report
