I admit, I didn't look into that much; I just skimmed through some overrides of `List.sort`. That said, does it mean that before `List.sort`, `Collections.sort`, which had the same implementation that the default `List.sort` now has, would not be able to be properly sort `CopyOnWriteArrayList`?

(Sorry, if I digress.)
