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.

If we would treat negative values as 0, we loose a chance, where programmers could become aware
about possible errors in the logic of their program.
