EAR打包环境下JAR中JSF ManagedBean的@PostConstruct未触发问题

我知道类似问题已经有过讨论，但我的场景有点特殊，想请教大家：我把包含ManagedBean的JAR和需要解析JAR内视图资源并调用该Bean的WAR，一起打包在了EAR里，结果出现了Bean的@PostConstruct方法未触发的问题。

我的运行环境 #

• Weblogic 12c
• JSF版本：jsf_2.0.0.0_2-1-20.jar（由Weblogic自带）

JAR的目录结构与配置 #

JAR里的faces-config.xml放置位置是正确的，完整目录结构如下：

对应的ManagedBean代码 #

这个Bean的@PostConstruct注解标注的init()方法完全没有触发，代码如下：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */
package gt.com.late.security.;

import java.io.IOException;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Map;
import javax.annotation.PostConstruct;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;
import org.primefaces.context.RequestContext;
import org.primefaces.model.menu.DefaultMenuItem;
import org.primefaces.model.menu.DefaultMenuModel;
import org.primefaces.model.menu.DefaultSubMenu;

/**
 *
 * @author 
 */
@ManagedBean(name="menu", eager = true)
@SessionScoped
public class Menu {
    private String ...
    private String ....

    /**
     * Creates a new instance of Menu
     */
    public Menu() {
    }
    
    @PostConstruct
    public void init(){
        /* This doesn't trigger */
    }
}

WAR的资源解析配置 #

WAR是通过FaceletsResourceResolver来获取JAR内的视图资源的，这部分功能运行正常，配置如下：

<context-param>
  <param-name>facelets.RESOURCE_RESOLVER</param-name>
  <param-value>com.example.FaceletsResourceResolver</param-value>
</context-param>

想请教下，在EAR环境下处理这种JAR+WAR的组合场景，是不是存在什么特殊的差异导致@PostConstruct方法没触发？
