Arrays.asList(primitive[]) #208

For example, Arrays.asList(int[]) returns a List<int[]> where many people expect a List<Integer>. An appropriate substitute would be to use Guava's Ints.asList(int[]), and so on for the other primitive types.

For any case where the user actually wanted a List<int[]> (and don't want to modify it) we should make them use Collections.singletonList() instead to avoid the extreme confusion.

I'm curious what people are doing with these things though; they might be trying to reinvent various Arrays methods and such.
