This is because JMS semantics require the temporary node to have a lifetime
scoped to the session (not a link), so the JMS client has to create a
synthetic link which it uses simply to manage the lifetime of the dynamic
node. In order to not cause unintentional assigning of messages to a link
that will never actually be used for consumption, a sending link is used.
Note that in general JMS would expect that you should be able to send to a
temporary queue created in this way (since the point of temporary queues is
to use as a reply to)

And this really isn't something you'd be expecting a generic client (like
the JMS client) to know :-)
