Weld 2.4.4.Final causes test failures on WFLY. The test is an EAR without WAR but it has a library and one EJB jar; both of these observe @Initialized(AppplicationScoped.class). See WFLY-3334 for more information on that.

The real problem is that we have introduced a stricter check in WELD-2389 and only register a module if an integrator implements our Environments API by adding exactly same set of services. However, this is not the case with WildFly - see WildFlyWeldEnvironment (transaction services are missing in order to make it EE environment). As a result of that, Weld fails to register a non-web module (and therefore doesn't fire those events for it later on).

So there are two options here:

1. Revert the change in Weld and go back to lenient check to permit this behaviour.
2. Change code on WildFly side and try to "correct" this
