> [Broker-J] Changing queue exclusive mode throws exception
> ---------------------------------------------------------
>
> Key: QPID-8665
> URL: https://issues.apache.org/jira/browse/QPID-8665
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-broker-9.1.0
> Reporter: Daniil Kirilyuk
> Priority: Minor
> Fix For: qpid-java-broker-9.1.1
>
>
> If queue has a consumer and exclusive mode is set to CONNECTION, then
> changing queue exclusive mode to PRINCIPAL or CONTAINER will throw exception
> below. Then no consumer is able to consume messages from queue and broker's
> webgui fails to show Edit Queue dialog again.
> Steps to reproduce:
> * set queue exclusive mode to CONNECTION in broker's webgui
> * connect to queue
> * set queue exclusive mode to PRINCIPAL or CONTAINER in broker's webgui
> * exception should be thrown
