Description
The NDN packet format specification defines which TLV types codes are critical and cannot be ignored if unrecognized.
https://named-data.net/doc/NDN-packet-spec/current/tlv.html#considerations-for-evolvability-of-tlv-based-encoding
But the method TlvDecoder.finishNestedTlvs skips all remaining unrecognized TLV fields, including those with critical type codes. It should throw an exception by default with an optional flag to skip unrecognized critical type codes.
