[cdi-dev] Unexplained change in behavior between Java EE 6 and Java EE 7

We are investigating a change in behaviour between Java EE 6 and Java EE 7 and were wondering if this is a bug or a specification change;

If there is a RequestScoped bean and SFSB like below, and I call invokeStatefulService() on the Request Scoped Bean the behaviour changes depending on Java EE version;

On GFv3 and JBoss EAP 6 the method returns "init" implying we have 2 separate SFSB instances.
and on GFv4 and WildFly the method returns "stateFromFirst" implying there is 1 SFSB instance.

I would've imagined that the second result i.e. 1 SFSB as there is 1 client bean which exists for the duration of the call is the correct behaviour. However I am not sure.

As both appservers above use JBoss Weld for CDI is this a Weld bug or did the behaviour change between Java EE 6 and Java EE 7?

public class Injection {

    StatefulService first;

    StatefulService second;

    public String invokeStatefulService(){
        return second.getState();

public class StatefulService {

    private String state;

    public void init(){
        this.state = "init";

    public void setState(String state) {
        this.state = state;

    public String getState() {
        return state;
