Ok I yield. 
But you have to admit that making sure a signed int is always 0 or positive is probably the most common though low value usage you will find. And it's low value unless you factor security consideration at which stage it become a very very good idea to litter your code with these. 

@Positive
int age, nbrOfApples, nbrOfFriends, starRatingAverage, votingParticipants;

I'd go with default strict to true. It's supported by the mathematical definition of Positive/Negative number.

Very difficult to know the more common scenario (in a quick informal poll between developers near me everybody was confused).

I found this implementation of Zalando  for a monetary amount and they use the strict interpretation for @Positive/Negative annotations and they added @PositiveOrZero/@NegativeOrZero to include the 0  : https://github.com/zalando/money-validation#usage 

The Eclipse Collections (ex-Goldman Sachs collections) defines positive number > 0 (strict case), https://github.com/goldmansachs/gs-collections. I would say that the more common scenario is to exclude the 0.

My last response might have made sense if I'd have sent my previous
one (to Emmanuel) from the right address:

"Less common" is an opinion. Are there survey data to back it up? By
contrast, a literal or "strict" interpretation of past or future is
something that cannot be questioned.
