The processor only recognized a plain List<X> or a List<? super X> wildcard as a multivalued 'in' parameter, so the extends-bounded form produced by Kotlin was rejected and the finder method implementation was not generated. typeArgumentMatchesAttribute now also handles the extends bound, so a Kotlin List parameter reliably produces an 'in' condition like its Java equivalent.
