Description

All tag values (even byte/short) are currently read as a long value. That works fine as long as the value is padded with 0. Unfortunately, the very first file from production environment I tried to process with CCITTFactory failed, because short value was not padded with 0 (the complete tag data is 1201 0300 0100 0000 0100 3832 - little endian):
