>          Components: qpid-jms-client
>            Reporter: Jakub Scholz
> 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
