C# doesn't and I'm fairly sure Java doesn't either (though I'm certainly
no Java expert). Overall, I think this entire "call static method on
instance" deal comes from C++.
I haven't used C# much, so I'm not entirely surprised if I'm wrong about
that,
but I'm 99.99% sure that Java allows it. I definitely remember being
irritated
by it in Java.

Java allows it, but gives a warning and auto-correct option to use the
class reference instead, in Eclipse. That probably means that there is no
justifiable use-case for it.
