> -DISCLAIMER: this bug happens sometimes and then goes away, even using the simple test case I've attached. I would love to know why or how it comes and goes, but I just don't know. It has been happening for weeks, I was able to reproduce this morning using the attached project and procedure, and now ... everything works just fine. I'm pretty sure this isn't a false alarm, because we tracked down bugs in our software to this phenomenon, and everything got better when we disabled auto-delete of our queues. Anyway, here goes:-
> UPDATE: I figured out exactly what is the right sequence to reproduce.
> Configure Artemis to auto-delete queues.
> * there is a queue producer and queue consumer running in different processes
> * the producer sends a few messages, and the consumer drains the queue
> * quit the consumer process
> * enough time elapses that Artemis auto-deletes the queue
> * send a few messages from the producer
> * start the consumer process
> Expected: queue is re-created and consumer is delivered messages when it starts
> Actual: producer send() fails silently, queue is not re-created, consumer sees no messages
> To reproduce, build the attached maven project in scratch.zip. The version of java doesn't seem to matter - at least, Java 8 and 17 are the same.
> In separate consoles run
> {{java -cp target/scratch-10.0.1-SNAPSHOT-shaded.jar net.redpoint.test.TestSend}}
> {{java -cp target/scratch-10.0.1-SNAPSHOT-shaded.jar net.redpoint.test.TestConsume}}
> You will see something like
> !image-2022-11-09-14-33-14-216.png!
> Hit enter on the sending console, and it will send a message (or two, on Windows)
> !image-2022-11-09-14-33-54-881.png!
> Ctrl-C to kill the consumer but _leave the producer running_
> Bring up the Artemis console and browse queues
> !image-2022-11-09-14-36-41-631.png!
> Wait just long enough for the Artemis console to show that "myqueue" has been auto-deleted
> !image-2022-11-09-14-40-30-793.png!
> (or wait until the artemis command-line window logs that the queue was deleted)
> Hit Enter on the producer window. It will send a message.
> But.. the queue is not recreated, and the send() fails silently.
> Start the consumer again. It does not receive any messages.
