people say reflection is slow, but things that take <1ms in java take 300ms on kotlin reflection

KClassImpl has an inner class

Data

and this class takes ages to build. and it is built lazily before any other reflection call is possible

1ms:

val instanceField = jClass.getDeclaredField("INSTANCE")
            val obj = instanceField.get(null)
            val contexts = jClass.getDeclaredMethod("getContext").invoke(obj)

300ms:

return kClass.declaredMemberProperties.single { it.name == "context"
 }.call(kClass.objectInstance) as RootContext
