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,

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;
}
}
