Robbie Gemmell commented on QPIDJMS-443:
----------------------------------------
No, its unique (at a given point) per-session. I agree it is not explicitly
stated that way (nor is it stated its per-connection, or anything else), and is
instead just implicit in how the document outlines things overall. For example
earlier in the spec it outlines that the session(+link) handles attach and
detach, plus it is the session begin and not connection open that defines
'handle-max' which is per-session, plus attempts to concurrently use a handle
are defined as session-error and not a connection-error. I don't know of an
implementation that considers things otherwise.

> Hi,
> I found QPID JMS to not set the handle id [1] in the transport layer attach
> [2] of the AMQP 1.0 specification correctly when using two different sessions
> in two different threads. I tried to share one connection among two different
> threads. Within the threads, a new session and a new producer is created (I
> attached the code to reproduce the issue). If I capture the packets with
> Wireshark I can see that the handle id is set to 0 for both sender.
> If there is only one session created and shared among the two different
> threads two the handle id is set correctly.
> Even though for example a RabbitMQ does accept that I think this might be an
> issue as the AMQP 1.0 specification states the following:
> _The handle MUST NOT be used for other open links. An attempt to attach using
> a handle which is already associated with a link MUST be responded to with an
> immediate

> carrying a handle-in-use
> [session-error|http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#type-session-error]_
> I may misunderstand the specification.
