<@U223RM5CH> Well this just works: `val myInt: Int = Integer.valueOf(200)`.

What if `Int::class` may be provided via lambda? :thinking_face:

I don't know, what about it? Can you give an example?

Hold on, I'll look into my spaghetti codebase

```
val type = method.getAnnotation(On::class.java).value
builder.testCallback { route, it -&gt; it as Any; type.java.isAssignableFrom(it.javaClass) }
```
You may provide any class via annotation `@On`

Meanwhile it cast to any is necessary as at that particular spot it's a generic.

Hmm so your problem is that `isAssignableFrom` doesn't behave correctly?

You'll have to use `type.javaObjectType` if you want to always get the boxed class, which is the case here.

So `type.javaObjectType.isAssignableFrom(it.javaClass)`

Cheers. How would it behave with actual object types? Would it return like `it.java` would?
