Order of creating @Inject objects

Question

Look at following class (please note, that it is not a singleton):

public MyClass() {

    @Inject private A a;
    @Inject private B b;

}

What object will be created first a or b?

Is there a possibility of determine the order of creating objects?

Answer 1

I don't think so and I don't see a reason why it should matter (I am also afraid that order of object instantiation can change from deployment to deployment). You are guaranteed to have all objects injected in @PostConstruct and that's the most important thing (as far as I am concerned).

Answer 2

Actually, you can very much control order. First, assume that they have normal scopes (e.g. @RequestScoped). Second, make B have a reference to A. You'll see that A gets instantiated first, then B. Note that you'll need to track via your @PostConstruct method.
