Subject [jira] [Created] (ARTEMIS-1906) anycastPrefix and multicastPrefix should be kept in mapped addresses

Lionel Cons created ARTEMIS-1906:
------------------------------------

             Summary: anycastPrefix and multicastPrefix should be kept in mapped addresses
                 Key: ARTEMIS-1906
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1906
             Project: ActiveMQ Artemis
          Issue Type: Bug
            Reporter: Lionel Cons


For STOMP (at least), {{anycastPrefix}} and {{multicastPrefix}} are used to map destinations
to addresses and routing types.

In order to have compatibility with other brokers such as ActiveMQ 5 or RabbitMQ, these prefixes
must be set to {{anycastPrefix=/queue/}} and {{multicastPrefix=/topic/}}. With these settings,
a destination like {{/queue/foo}} works like a JMS queue while {{/topic/foo}} works like a
JMS topic. So far, so good.

Unfortunately, the current implementation removes these prefixes when mapping to addresses.
This means that the two (completely unrelated, see ARTEMIS-1794) destinations {{/queue/foo}}
and {{/topic/foo}} map to the exact same address named {{foo}}. Messaging does work as expected
because the same address can have multiple routing types but monitoring and security become
problematic.

Security is defined per address so the two destinations {{/queue/foo}} and {{/topic/foo}}
cannot have different security settings.

Similarly, some monitoring information is attached to the address objects so {{/queue/foo}}
and {{/topic/foo}} cannot have different monitoring metrics.

It seems all these problems would disappear if prefixes would be kept when mapping STOMP destinations
to addresses.

Note: similar problems might exist with other protocols but I've tested it only using STOMP.
