jsf - "IllegalArgumentException: Can not set [EJB interface] field [managed bean field] to com.sun.proxy.$Proxy[some number]"与 OmniFaces 的@Eager

Question

在 Payara 4.x 和 5.x、Glassfish 4.x 和 5.x 以及 WildFly 11.0.0.Final 上，将 EJB 注入(inject)多模块 Maven Java EE 7 项目中的 JSF 托管 Bean 中均失败这让我认为这不是我最初认为的 Payara/Glassfish bug [1]。

WAR 模块中的简单 JSF 支持 bean

@Named
@ApplicationScoped
@Eager
public class Init {
    @EJB
    private InitService initService;

    public Init() {
    }

    @PostConstruct
    public void init() {
        initService.init();
    }
}

在 JAR 模块中使用 EJB 接口(interface)

@Local
public interface InitService {

    void init();
}

以及EJB模块中的实现

@Stateless
public class DefaultInitService implements InitService {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void init() {
        Long id = 1L;
        MyEntity myEntity0 = entityManager.find(MyEntity.class, id);
        if(myEntity0 == null) {
            myEntity0 = new MyEntity(Long.MIN_VALUE, "myProperty");
            entityManager.persist(myEntity0);
        }
    }
}

在 Payara 4.1.2.174 上失败的原因是

这是 How to use OmniFaces @Eager annotation with PrimeFaces? 的前面，但与 https://github.com/payara/Payara/issues/2237 不同，因为在该问题中，即使正确配置了日志记录，我也没有收到任何异常或其他反馈。

通过引用的问题可以轻松找到在普通 Docker 镜像上重现问题的示例项目和 GitLab CI 输出(不同分支上的不同 AS 以及相应 CI 管道部分上的输出)

[1] 在 https://github.com/javaee/glassfish/issues/22401 和 ojit_a 上报告了一个更简化的示例，该示例也与代理类转换异常相关，但堆栈中没有涉及焊接。

Answer 1

...Proxy 类强制转换异常问题是由 JAR 模块的 Maven compile 范围引起的(包含位于 WEB 和 EJB 模块旁边的实体和 EJB 接口(interface)，其中包含EJB 实现)在 WEB 模块中。这会导致 EJB 接口(interface)类由不同的类加载器加载(这在此 Java EE 设置中是正确的)，以便根据类加载器工作方式的定义将它们视为不同的类。

可以通过在 WEB 模块中将范围更改为 provided 来避免此问题，且没有任何缺点。

应用程序服务器(GlassFish 和 WildFly 以及可能的其他)的反馈与许多(Java EE)技术一样可怕，我建议改进，尽管我明白黄金法则是，如果您的应用程序正常工作，那么您'已经完成了 20% 的工作，现在您需要处理剩余 80% 的工作，以便在所有可能的情况下获得有用的反馈，这需要一些时间(意味着几十年)才能实现。
