kotlin reflection for java method accepting null Class array

I have java code like this:

 Method m = device.getClass()
        .getMethod("removeBond", (Class[]) null);
    m.invoke(device, (Object[]) null);

and i am trying to write the same thing in kotlin like this:

device.javaClass.getMethod("removeBondNative", null as Class<*>).invoke(device, null as Any)

but i get this error message:

                                                                           kotlin.TypeCastException: null cannot be cast to non-null type java.lang.Class<*>

i also tried changing null to Unit:

device.javaClass.getMethod("removeBondNative", Unit as Class<*>).invoke(device, null as Any)

but still encounter error:

what i am doing wrong here? how can java reflection be mirrored in kotlin in a situation like this?
