NPE во время навигации с bean-компонентом с областью просмотра с использованием Mojarra 2.2.x с openwebbeans 1.0 (CDI 1.0)

Теперь я столкнулся с проблемой ViewScope на h: commandButton с навигацией. Я не уверен, поддерживается ли JSF 2.2 с CDI 1.0

Минимальный воспроизводимый пример в среде Tomcat 8.5 test.x html -> кнопка «ajax работает» работает, кнопка «h: commandButton non- ajax» не работает

  1. Не работает с версией Mojarra jsf-api -2.2.13 & jsf-impl-2.2.13
  2. Не работает с версией Mojarra javax.faces-2.2.20
  3. Работает с версией myfaces myfaces-api-2.2.12 и myfaces-impl -2.2.12
  4. Работает с версией omnifaces omnifaces-1.8.3 org.omnifaces.cdi.ViewScoped (необходимо было добавить дополнительный jar validation-api-1.1.0.Final)

TestView. java

package com.lean.demo;

import java.io.Serializable;

import javax.faces.view.ViewScoped;
import javax.inject.Named;

@Named
@ViewScoped
public class TestView implements Serializable {

    public String goNextCase1() {
        System.out.println("goNextCase1");
        // Add navigation-case with <redirect />
        return "PageTestView2";
    }

    public String goNextCase2() {
        System.out.println("goNextCase2");
        return "test2.xhtml?faces-redirect=true";
    }

    public String goNextCase3() {
        System.out.println("goNextCase3");
        return "test2.xhtml";
    }
}
