-----------------------------------
Yeah I fear it might only occur in combination with Apache Shiro...
> 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!
