Hi,

 

I agree that there should be two instances of the stateful bean, so GF3/EAP6 is correct.

 

It's remarkable then that seemingly GF4 and WF8 have the exact same integration regression.

 

At any length this would be a good case for adding an extra test to the TCK ;)

 

Kind regards,

Arjan

Hi Steve,

this is not caused by a change in the specification nor in Weld. It is probably a regression in GlassFish integration. The correct behavior is the former (2 instances) as that is aligned with how @Dependent instances work in general. If you need the bean instance to be shared across injection points, you can give it a scope other than @Dependent.

HTH,

Jozef

Hi

 

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?

 

@RequestScoped

public class Injection {

   

    @Inject

    StatefulService first;

 

    @Inject

    StatefulService second;

   

    public String invokeStatefulService(){

        first.setState("stateFromFirst");

        return second.getState();

    }

}

 

@Stateful

public class StatefulService {

   

    private String state;

   

    @PostConstruct

    public void init(){

        this.state = "init";

    }

 

    public void setState(String state) {

        this.state = state;

    }

 

    public String getState() {

        return state;

    }

}
