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;
}
}
