Artemis in EAP supports diverting and transforming of diverted messages using the custom implementation which implements Transformer interface [1]. The interface was changed between EAP 7.1 (Artemis 1.x) and EAP 7.2 (Artemis 2.x).

public interface Transformer {

- ServerMessage transform(ServerMessage message);
+ Message transform(Message message);
}

Customer impact: Customers have to update and recompile their custom modules which implements the Transformer interface.
