For this PR, the simplest thing is to revert the changes to HexDigit, remove jdk.internal.digits.Hex256 and just put a small holder class in UUID for use by UUID.toString. That would be my preference to avoid splitting up HexDigits and creating inconsistencies in code used for string templates. ------------- PR Comment: https://git.openjdk.org/jdk/pull/14578#issuecomment-1609843786
