Yes, I've been careful to put it in a Java-only block so as not to alter the specification of the problem

Hi! Thanks for the feedback.

Well, It's true that it doesn't mention anything, because in the initial kata it didn't specify that case, except in the last example. But that input is indeed considered and valid.

I will specify it at the description and also I can instantiate a single static Random for the performance problem.
