the problem is that if you try to check from java: (1L as Any)::class.java.isAssignableFrom(Long::class.java) returns false

If you want to use just java reflection, you have to consider corner cases like that.

[ilya.gorbunov]

With kotlin reflection (requires kotlin-reflect dependnecy) you can check someLong::class.isSubclassOf(Long::class) or vice versa.

Hmm well with Java reflection I could understand that a java Long/long won't work in that case with a Kotlin Long

[aballano]

but this case seems like an optimization done by the compiler that is far from explicit

[aballano]

because this works (1L)::class.java.isAssignableFrom(Long::class.java)

[aballano]

so I don't think is just a corner case
