Incorrect error handling when the sender.send(...) call / message transfer causes an error

It seems to me that the error handling doesn't work properly when sending a message triggers an error (i.e. the sender.send(...) call, not creating sender).

On the C++ broker, it is easy to configure the access control to allow message producers to send messages to a certain exchange (topic) only with some particular subjects / routing keys. When the subject / routing key is wrong, the C++ broker will raise "unathorized access" error and detach the link.

I was running this scenario from the Qpid JMS client and it seems that it doesn't handle the error well:
1) Connect with the JMS client to the C++ broker
2) Open a sender to an exchange on the broker (this has to be allowed in the ACLs on the broker)
3) Try to send message with subject (i.e. JMSType) which is not allowed in broker ACLs
4) The broker detaches the link and the Proton library in the client seems to handle it, but the client doesn't seem to raise any exception to the outside.

When sending messages asynchronously in a loop, the send(...) call will finish and few "sent" message later it will throw at least "javax.jms.JMSException: send not allowed after the sender is closed." exception. It doesn't contain the original error, but at least it is clear that something went wrong. So I think that is quite OK.

But when sending messages synchronously, it seems to get stuck in the send(...) call and never return, although the underlying session is already gone. I would expect that the send(...) call returns and either throws some exception directly or through the Exception Listener.
