James Birdsall commented on QPID-2167:
--------------------------------------

Trying to check whether an exchange exists, actually.

It looks like this is expected behavior for declare(passive=true), yes, based 
on page 217 of the AMQP 0-10 spec. Sorry about the false alarm there.

However, exchange.query, on page 219, is not documented as raising a not-found 
exception  -- it's not documented as raising any exceptions at all. It does 
have a "not-found" field in the return structure, though, and there's a 
getNotExists() method on the return type for session.queryExchange() in the 
Qpid C++ client. Am I missing something?

> In a program using the C++ client, running against the C++ broker, trying to 
> do a session.exchangeQuery or session.exchangeDeclare (with passive=true) on 
> a nonexistent exchange throws a not-found exception. Thereafter, any other 
> operations on the same session throw the same exception again, including 
> trying to close the session.
