One possibility could be that there is no applicationInformation in the PDU,
as size of applicationInformation could be 0 too, and data after "80 00" may
be any other PDU.
Also, when I removed "00" from the erratic part "80 00 01 20 40", I could
decode applicationInformation without any error. So, there may be a
possibility that data was encoded incorrectly.
