I agree with Claes' comment suggesting that IAE for negative
lengths is a pain
and defining it to append 0 would be natural in many use cases.
OTOH, inserting a simple Math.max(n, 0) instead of n where n could get
negative would achieve the same without complicating the expression too
much. Java standard APIs have a tradition of being explicit rather than
having implicit hidden logic which surely shortens many usecases, but
makes them harder to read and understand for casual readers not
intimately familiar with such API. The logic to treat negative lengths
as 0 is implicit and not universally correct.
