Constraint collectors: LocalDateTime breaks max()

      This works:

      Function<Job, Duration> f = (Job job) -> (Duration) job.getDuration();
UniConstraintCollector<Job, ?, Duration> max = ConstraintCollectors.max(f);

      This doesn't compile:

      Function<Job, LocalDateTime> f = (Job job) -> (LocalDateTime) job.getEndDateTime();
UniConstraintCollector<Job, ?, LocalDateTime> max = ConstraintCollectors.max(f);
