Github user grs commented on the issue: https://github.com/apache/activemq-artemis/pull/2392 Two points: 1) in my case, accessing over AMQP, the sender is *not* defining any routing type 2) I would not expect a sender requesting a routing type explicitly to redefine a statically defined address i.e. if address pre-exists and has routing types only multicast, a sender attempting to request anycast should be informed that their intentions do not match the pre-configured semantics (of course if the address does not exist then it can be defined according to the senders desires providing auto-creation of the address is allowed).
