[jira] [Commented] (QPIDJMS-376) notify the ExceptionListener when a consumer with a MessageListener remotely closes

    [ https://issues.apache.org/jira/browse/QPIDJMS-376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16487394#comment-16487394 ] 

Daniel Maier commented on QPIDJMS-376:
--------------------------------------

Sorry [~gemmellr] for the late feedback.

I tested the fix together with DISPATCH-962. It works now fine for me for initial connect, i.e. if link gets closed from qdrouter while receiver link establishment I get an exception in my 
exception listener.

However I am not sure if the failover behavior is correct. I run into the following corner case:

- configure JMS client with infinite failover
- set consumer message listener
- start connection to qdrouter
- connection succeeds and receiver link gets established
- stop qdrouter and delete address to which the JMS client is connected to
- start qdrouter again
- JMS client re-connects to qdrouter and also tries to re-established receiver link
- As address does not exist qdrouter closes link
- JMS client does not try to re-established receiver link any longer and also my exception listener does not get called

Is this behaviour intended? As failover stops and no exception listener gets called I have no chance to react to this siutation in my code and my JMS client does never recover from this state.

> When I create a consumer to an address that just does not exist, I expected to get some exception or that the client retries the operation. But there seems not even to be a log message which indicates a failure.
> Is this intended behavior or is this a bug? A more general description is: If AMQP server closes the receiver link, qpid jms client does not notify the user anyhow or does not re-establish the link.
