You don't need to in this instance.  values() and getEnumConstants() 
both return an array of the proper type, so the dirty work has been done 
for you.

Actually, "don't mix arrays and generics" is far to strong.  There's no 
reason not to mix them.  There's only a couple of edge cases where you 
have to do funny things with compiler directives.  Your usage here is 
just fine.
