Result of the `checkNotNull` calls should always be a non-nullable values. The simplest idea how to acheive it is adding not-nullable Any bound to the type parameter declaration. Existing comment stating about impossibility of such bound seems to be not 100% correct because it doesn't take into account presence of definitely-non-nullable X & Any types that allow described case with nullable generic. ^KT-55804 Fixed
