FacesMessages may trigger NPE in JSF code

                 Key: JBSEAM-4827
                 URL: https://issues.jboss.org/browse/JBSEAM-4827
             Project: Seam 2
          Issue Type: Bug
          Components: JSF Integration
    Affects Versions: 2.2.2.Final
            Reporter: Stephan Bublava

FacesMessages.beforeRenderResponse() passes the return value of FacesMessages.toFacesMessage() to FacesContext.addMessage() without any checks.

The problem is that toFacesMessage() may return null and FacesContext.addMessage() does not allow that. (See http://download.oracle.com/docs/cd/E17802_01/j2ee/javaee/javaserverfaces/2.0/docs/api/javax/faces/context/FacesContext.html#addMessage(java.lang.String,%20javax.faces.application.FacesMessage)
