CODI with ejb stateless on Websphere liberty profile 8.5.5

问题

I cannot launch a webapp that embedd CODI on websphere liberty profile 8.5.5 if the webapp contains a @Stateless ejb.

I get this exception:

[ERROR   ] null

I've constated that the problem occurs only if an ejb is present in the project (in my case a @Stateless ejb).

In this case, the application context is initialized when the server is started and the webapp installed/deployed. No problem here.

When the first HTTP request is handled by the webapp, the FacesServlet is initialized and CodiNavigationHandler is instanciated.

The method CodiNavigationHandler.isAddViewConfigsAsNavigationCaseActivated() is called in the constructor and tries to get a reference on CODI JsfModuleConfig. This JsfModuleConfig has an @ApplicationScoped annotation and the the beanManager tries to get the application context.

This application context has already been created (when the webapp is deployed) but the LibertyContextsService.initApplicationContext(String)has not been called yet. So the application context is null on the LibertyContextsService.applicationContexts ThreadLocal variable and the error occurs:

WebBeans context with scope type annotation @ApplicationScoped does not exist within current thread

To reproduce:

create a Dynamic Web Project
add an almost empty beans.xml under WEB-INF (just a beans element)
add an almost empty faces-config.xml under WEB-INF (just a faces-config element)
add a web.xml with a faces/index.xhtml
copy codi jars in WEB-INF/lib (http://www.apache.org/dyn/closer.cgi/myfaces/binaries/myfaces-extcdi-assembly-jsf20-1.0.5-bin.zip)

add a stateless bean:

import javax.annotation.PostConstruct;
import javax.ejb.Stateless;

@Stateless
public class MyBean {

    @PostConstruct
    public void postConstruct() {
        System.out.println("post construct: " + this);
    }

    public String getTitle() {
        return "test";
    }
}

add a jsf bean:

import javax.inject.Inject;
import javax.inject.Named;

@Named
public class MyController {

    @Inject
    private MyBean myBean;

    public String getTitle() {
        return myBean.getTitle();
    }
}

add a simple jsf web page with:

<h:body>
    <h:outputText>${myController.title}</h:outputText>
</h:body>

nota: if you remove the @stateless on the ejb, the application works.

Effectively it seems to be a bug (I also post the question on IBM forums: https://www.ibm.com/developerworks/community/forums/html/topic?id=f372bbc5-5ba4-4c2a-9ef0-0bdcd76766da#09228314-2baf-4892-899e-5a8cc52daa19).

I'm going to try to find a way to create a PMR (I'm in a big company, difficult to find the right person that will grant me access to that).

So for now, I've switched to jboss.
