>                 Key: ARTEMIS-1611
>                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1611
>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 2.4.0
>         Environment:  
>  
>            Reporter: Jeff Mesnil
>            Priority: Major
>
> We have users of Artemis 1.x that uses the transformer interface defined in org.apache.activemq.artemis.core.server.cluster.Transformer.
>  
> This class was moved in Artemis 2.x in an incompatible way: [https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/server/cluster/Transformer.java] that
redirects to [https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/server/transformer/Transformer.java]
> We are updating Artemis 2.x but it breaks the client configuration that was using the
old interface.
> We have strong requirement for backwards compatibility and we'd like to come up with
a solution so that the new interface could be made backwards compatible with the existing
one.
> Would it be possible sense to reintroduce the old interface in the server.cluster package
so that old code would still be able to run with Artemis 2.x?
