[jira] [Commented] (QPIDJMS-443) Wrong handle id in AMQP 1.0 attach
transport layer, when using different sessions and producer among different
threads
[ https://issues.apache.org/jira/browse/QPIDJMS-443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16751019#comment-16751019 ]
morten commented on QPIDJMS-443:
--------------------------------
So a handle id must not be unique within the connection? I cannot find something about this in the specification.

> 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 [close|http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#type-close] 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.
