For some reason Kotlin doesn't automatically generate JVM interface default methods by default, and you have to enable it with a compiler flag. In a few interfaces, I've provided a couple default overload specializations of a method (i.e. plan.directives() and directives(type) delegate to directives(type, deserializer)). If you implement the interface in Kotlin, you don't have to override the overloads. But in Java you do, unless we have this flag.
Verification
I tested this by converting the NotImplementedPlan test stub from Kotlin to Java.
