What I was mainly getting at is:
Should the cases of existing ConcurrentMap methods and the new
function-accepting methods work differently? Suppose
someone calls computeIfAbsent on a JDK7-compliant
(but non-JDK) ConcurrentMap that doesn't have an explicit
override. They would get the non-atomic version. And this is
considered OK according to the the specs as I wrote them.
But still surprising to at least some users.
