In #790 I introduced
IOUtils#checkIndexFromLengthcalls to validate arguments across the codebase. Ironically, theIOUtilsclass itself was left out.This PR addresses that omission by adding argument validation to
IOUtils#readandIOUtils#readFully.Key points:
Ensures consistency with the rest of Commons IO by validating
offsetandlength.Fixes inconsistent exception behavior:
length < 0resulted in anIllegalArgumentException.offset < 0did not trigger validation and failed later with anIndexOutOfBoundsException.With this change, both invalid cases are handled consistently and upfront.
