(Mockito + Kotlin) eq() and any() in Android Test returns null

Things are going fine in test package, however, they are going wayward in androidTest package.

Things I have already tried:

Instead of Mockito.any() I have already tried following snippet

fun <T> any(): T {
    Mockito.any<T>()
    return uninitialized()
}
private fun <T> uninitialized(): T = null as T

This also returns null in case of androidTest, however it runs fine in test package

I have also tried nhaarman's mockito-kotlin that didn't help either

Any help will be highly appreciated.
