[weld-dev] Weld Probe not initalized during AfterDeploymentValidation

[Benjamin Confino]

Hello

I've been seeing probe not initalized exceptions that occur on CDI 2.0 but 
not CDI 1.2, from what I can see when I debug into the issue the problem 
occurs in 
TransactionalObserverNotifier(ObserverNotifier).notifySyncObservers

In CDI 1.2 I see that the the ArrayList observers has two entries, the 
first being ProbeExtension.afterDeploymentValidation

In CDI 2.0 I see four entries, with the first being 
org.apache.myfaces.cdi.config.FacesConfigExtension

And when the afterDeploymentValidation method of FacesConfigExtension is 
called the result is org.jboss.weld.exceptions.IllegalStateException: 
PROBE-000005: Probe is not properly initialized. I've attached a stack 
from that error: 


And the source is on github: 
https://github.com/apache/myfaces/blob/master/impl/src/main/java/org/apache/myfaces/cdi/config/FacesConfigExtension.java

So what are the options here? I don't see anything under 
http://docs.jboss.org/cdi/spec/1.2/cdi-spec.html#after_deployment_validation 
saying that you shouldn't invoke beans during after deployment validation 
observers. A bit earlier in 11.5 it says "If other beans are injected into 
an extension’s observer methods, non-portable behavior results" but it's 
not clear if that refers to using the injected bean manager to lookup a 
bean. 

Presumably if weld-probe needs to run first there's some code to ensure it 
does? Do we need to do something to integrate with that code, or avoid 
integrating myfaces?

Regards
