well this works,

val primitive = v[0]!!::class.javaPrimitiveType != null
            v.add(
                if (primitive) {
                    when (v[0]!!) {
                        is Int -> 0
                        is Boolean -> false
                        is String -> ""
                        else -> null
                    } as E
                } else {
                    v[0]!!::class.java.newInstance() as E
                }
            )

provided v has an initial index
