> In {{PagingState.java}}, {{index}} is an integer field, and we add long
> values to it without a {{Math.toIntExact}} check. While we’re checking for
> negative return values returned by {{getUnsignedVInt}}, there's a chance that
> the value returned by it is so large that addition operation would cause
> integer overflow, or the value itself is large enough to cause overflow.
