Hi Gorden,
I have set the PN_TRACE_FRM=1 environment variable and I can see that the
"status" property is indeed included in the message sent. However, it seems
to be encoded as a 64bit integer, i.e. as an AMQP 1.0 long. The consumer,
however, expects it to be an AMQP 1.0 int. Is there a way to specify that
the value (200) should be encoded as an int instead of a long?
