> Var16Char, VarBinary, VarChar and VarDecimal vectors contain a UInt4 offset
> vector. When reading values into the corresponding holder, the values of
> their offset vectors are written into the "start" and "end" fields as
> ordinary integers. In the subsequent operations is not considered that
> originally this values were unsigned integers and (for example in the
> calculation of the buffer size at ParquetOutputRecordWriter) usual
> subtraction "end" - "start" used. This causes the target buffer size to be
> negative.
