Java makes it "work" by doing runtime manipulation of interface/class 
handles whenever they are used. This is too inefficient for a native 
compiled language.

Consider this:

   int can be implicitly converted to long.
   Therefore, shouldn't int[] be usable as a long[]?

It's an exactly analogous situation.
