Hi, I just realised the Collections.sort(List) method 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, no!) Or, what am i missing? Best regards, Piotr
