Josh Byster updated ARTEMIS-4787:
---------------------------------
Summary: Anycast queue does not auto-create if already multicast queue on
same address (was: Queue does not auto-create if already topic on same name)
> Anycast queue does not auto-create if already multicast queue on same address
> -----------------------------------------------------------------------------
>
> Key: ARTEMIS-4787
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4787
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Reporter: Josh Byster
> Priority: Major
>
> As a preface, I am aware that creating both anycast and multicast queues on
> the same address are an anti-pattern and not recommended. However, this is
> causing difficulties migrating over legacy clients from using Classic to
> Artemis.
> If one creates a JMS topic on an address, and then tries to create a JMS
> queue, it fails to create. However, if the order is flipped (creating a
> queue, then a topic), there is no exception.
> It seems like the issue is in this area of ServerSessionImpl:
> {code:java}
> Bindings bindings =
> server.getPostOffice().lookupBindingsForAddress(unPrefixedAddress);
> if (bindings != null && bindings.hasLocalBinding() &&
> !queueConfig.isFqqn()) {
> // The address has another queue with a different name, which
> is fine. Just ignore it.
> result = AutoCreateResult.EXISTED;
> {code}
> Please see test below to reproduce, which throws the exception immediately as
> seen in production.
> {code:java}
