Answer 1

As it described in the Kotlin reference

To make Kotlin APIs work in Java we generate Box as Box for covariantly defined Box (or Foo for contravariantly defined Foo) when it appears as a parameter.

You can use @JvmSuppressWildcards for avoiding it, just as following:

@Inject lateinit var foo: Set<@JvmSuppressWildcards Foo>
