> The attached patch makes ReflectionUtils.newInstance use generics
> appropriately. I've also gone through and updated everywhere that calls
> ReflectionUtils.newInstance to remove now-redundant casts, or to add further
> generics where appropriate. The overall result is about 17 fewer
> @SupressWarnings("unchecked") needed in the source tree.
