I found QPID JMS to not set the handle id  in the transport layer attach  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 close carrying a handle-in-use session-error
I may misunderstand the specification.
