Today I realized the Collections.sort(List) ceased to be stable as of Java
8 (sort of).
Although the method's documentation still promises stable sort, the
implementation delegates to List.sort(Comparator) and that interface method
bears no constraint that an implementation must sort stable.
Is "stable" missing from List.sort's documentation?
Or, instead, should it be now no longer promised by Collections.sort? (oh,
Or, what am i missing?
