Description

Qpidd throws an error

2015-01-14 16:15:43 [Broker] error 
qpid.10.0.0.1:5672-10.1.1.1:11292: 
Expected descriptor of type ulong or symbol; found 0 
(/home/chug/svn/qpid/cpp/src/qpid/amqp/Decoder.cpp:301)

when it receives the following byte stream from Amqp.Net Lite:

  00 53 77 73 00 00 00 41

As I interpret the stream it means:

  00          - constructor
  53          - smallulong, fixed-width, 1 byte value
  77          - amqp-value, section contains a single AMQP value
  73          - utf32, fixed-width, 4 byte value
  00 00 00 41 - 32-bit 'A'

AmqpNet.Lite is trying to send a single utf character and the stream makes sense. But both Qpidd and Wireshark AMQP dissector have a problem with this input stream.

Can any AMQP gurus offer an opinion?
