Subject [jira] [Issue Comment Edited] (AMQNET-369) Seems like there is a race condition that can lead to an InvalidDestinationException for tempoary queues after failover has resumed

This code determines if the temp destination is active so for some reason tempDests can't
contain dest.

{code}
        internal bool IsTempDestinationActive(ActiveMQTempDestination dest)
        {
            if(this.advisoryConsumer == null)
            {
                return true;
            }

            return this.tempDests.Contains(dest);
        }
{code}

    This code determines if the temp destination is active so either advisoryConsumer must
be null for some reason or tempDests doesn't contain dest.

        internal bool IsTempDestinationActive(ActiveMQTempDestination dest)

>             Project: ActiveMQ .Net
>          Issue Type: Bug

> If I repeat the test below I sometimes get a:
> Apache.NMS.InvalidDestinationException: Cannot publish to a deleted Destination: temp-queue://ID:Duracell-61594-634642411329432145-1:0:1
> Test:
> 1. Start Message bus
> 2. Start server code.
> 3. Stop Message bus
> 4. Start Message bus
> 5. Start client code.
> The client/server uses the request/response pattern.
> I don't have a unit test since it doesn't happen all the time. But if happens often enough
that I am sure there is a race condition bug here
> somewhere. And I think it's in NMS since I can see these log lines:
> AdvisoryConsumer adding: temp-queue://ID:Duracell-61594-634642411329432145-1:0:1
> ...Get InvalidDestinationException here...
> AdvisoryConsumer removing: temp-queue://ID:Duracell-61594-634642411329432145-1:0:1
