> Earlier code did not handle possible negative values for array index, and latest code handles the case.
> Following is the check that handles negative index value. Based on code review, I see an issue with code when (versions.length == val).
> {code}
> if (val < 0 || versions.length < val) {
>  return FUTURE;
> }
> WriterVersion result = versions[val];
> {code}
> In case versions.length == val, it should still throw ArrayIndexOutOfBoundsException
