Thomas Andraschko commented on MYFACES-4587:
--------------------------------------------
Do you use a EAR?
EAR is always a bit buggy with classloading and getting the right beanmanager
we had many bugs in the past in deltaspike
maybe you can try to check if myfaces pick ups the right beanmanager in
FacesInitializerImpl#initCDIIntegration
> Intermittent deployment error on WildFly 27
> -------------------------------------------
>
> Key: MYFACES-4587
> URL: https://issues.apache.org/jira/browse/MYFACES-4587
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 4.0.0
> Environment: Windows 10, WildFly 27.0.1
> Reporter: Manuel K
> Priority: Major
> Attachments: stacktrace.txt
>
>
> When deploying our JSF application using MyFaces on WildFly 27.0.1, we
> intermittently get the following exception:
> {code:java}
> org.jboss.weld.exceptions.IllegalArgumentException: WELD-001456: Argument
> bean must not be null{code}
> I have attached the full stack trace.
> Debugging leads me to CDIUtils#get, where the following statement returns an
> empty set:
> {code:java}
> bm.getBeans(clazz); // clazz is ClientWindowScopeContextualStorageHolder{code}
> It doesn't happen on every deployment but too often to ignore. Do you have
> any insight on this?
> It happens whether
> _org.apache.myfaces.annotation.USE_CDI_FOR_ANNOTATION_SCANNING_ is _true_ or
> _false_ (just a wild experiment) and the following in the web.xml (another
> wild experiment):
> {code:java}
> <servlet>
> <servlet-name>Faces Servlet</servlet-name>
> <servlet-class>jakarta.faces.webapp.FacesServlet</servlet-class>
> <load-on-startup>1</load-on-startup>
> </servlet>{code}
> Thank you very much in advance!
