You're turning "attempts" into "retries" here I'd say. If it's called 'attempts', shouldn't 0 mean an error (IllegalArgumentException), and 1 to attempt exactly once?
That is, unless we rename the whole thing to "retries" in the code, but it's currently named "attempts".

[VaderKai]

so we need do a choice,the utils name is RetryUtils,we can rename the method name or forbidan 0 attempts params,
i think rename is more reasonably,but changes is big,do you thinking about it?

I would personally keep it as attempts, so 0 means error, and 1 means try exactly once. But it depends what @langchain4j thinks

I've changed the number of attempts to a minimum of 1, and 1 for illegal parameters (<=0).
