It's a long roadmap, but this is their ultimate objective. Once java has value classes, future carrier classes and member patterns, that's when we shall see some very huge interest for java in ML. Also, they plan to introduce typeclasses in which it will be convenient to introduce operator overloading, and collection/array literals etc syntax. The idea is to unify the types in java, and then enable much stronger semantics to ensure data oriented programming becomes ergonomic in java.
