Memory leak with JSF and view scoped beans in EAP 6

Issue

• When a jsf action invalidate the current session and redirect to the current page, a referred view scoped managed bean leaks.
  SessionController:

public class SessionController {
    public void invalidateSession() throws Exception {
        ExternalContext externalContext= FacesContext.getCurrentInstance().getExternalContext();
        externalContext.getSessionMap().clear();
        HttpSession session = (HttpSession) externalContext.getSession(true);
        session.invalidate();
    }
}

LogoutController:

@RequestScoped
@ManagedBean
public class LogoutController {
    @Inject
    private SessionController sessionController;
    public String logout() throws Exception {
        sessionController.invalidateSession();
        // return to the start page
        return "/index.xhtml?faces-redirect=true";
    }
}

MyPageController:

@ViewScoped
@ManagedBean
public class MyPageController {
...
}

index.xhtml

...
<h:outputText value="Amount:"></h:outputText> <h:outputText value="#{myPageController.amount}" ></h:outputText>
...
