glassfish embedded v4.1.1和lambda

Question

我有一個junit測試（集成測試）與嵌入式glassfish服務器。如果我在無狀態的ejb中使用lambda，我的測試失敗。沒有lambda表達式，我的測試工作正常。

嵌入式glassfish服務器是否有任何修正或快照版本？我還沒有發現有關GlassFish的嵌入，所有:(

使用依賴快照版本的任何信息：

<dependency> 
    <groupId>org.glassfish.main.extras</groupId> 
    <artifactId>glassfish-embedded-all</artifactId> 
    <version>4.1.1</version> 
    <scope>test</scope> 
</dependency> 

如果我取消對該行（1）或（2），那麼我的例子豆的參考在我的JUnit測試空（出現查找失敗除外）:(

豆/ EJB：

@Stateless 
@LocalBean 
public class ExampleBean { 

    @PersistenceContext 
    private EntityManager em; 

    public Person get(Long id) { 
     Optional<Person> p = Optional.ofNullable(em.find(Person.class, id)); 

     List<Person> persons = new ArrayList<>(); 
     persons.add(p.get()); 

     // (1) properties.forEach(person -> System.out.println(person)); 
     // (2) String name = person.map(Person::getName).orElse(null); 
     //System.out.println(name"); 
     return p; 
    } 
} 

測試類：

public class ExampleBeanTest { 
    @EJB 
    private static ExampleBean examplebean; 
    private static Context context; 
    private static EJBContainer container; 

    @BeforeClass 
    public static void init() { 
     Map<String, Object> props = new HashMap<String,Object>(); 
     props.put(EJBContainer.MODULES, new File[]{new File("target/test-classes"), new File("target/classes")}); 

     try { 
      container = EJBContainer.createEJBContainer(props); 
      context = container.getContext(); 
      examplebean = (ExampleBean) context.lookup("java:global/classes/ExampleBean"); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

    @AfterClass 
    public static void tearDown() throws Exception { 
     if (container != null) { 
      container.close(); 
     } 
    } 

    @Test 
    public void testGet() throws NamingException { 
     assertNotNull(examplebean); 
     Person p = examplebean.get(1); 
     assertNotNull(p); 
     assertEquals("text", p.getName()); 
    } 
} 

是否有任何可以執行Java lambda表達式的juint test + java 8的嵌入式EE容器？

EDIT1： 我剛剛創建了lambda和經典迭代的另一個測試。經典迭代Bean運行正常，但forEach我有一個「查找失敗」異常。這裏發生了什麼？

public Person get(Long id) { 
    Optional<Person> person = Optional.ofNullable(em.find(Person.class, id)); 
    List<Person> persons = new ArrayList<>(); 
    persons.add(person.get()); 

    long l = persons.stream().count(); 
    System.out.println("length: " + l); // <- ok, result: 1 

    for (Person p : persons) { // <- ok, one result: "text" 
     String name = p.getName(); 
     System.out.println("name: " + name); 
    } 

    // if i keep the following line in my code i get a lookup failed exception 
    // if i comment these lines my code works fine 
    persons.forEach(pp -> { 
     System.out.println(pp.getName()); 
    }); 

return person.get(); 
}

EDIT2： 我可以在Maven日誌文件中看到NCLS部署-00009警告消息。只有一個相關的論壇主題發現：Glassfish deploy error 「Archive type of MyProject.jar was not recognized」。建議刪除lambda表達式。

難道是BUG？

是否有任何工作，嵌入式EE容器用JAVA 8 + EJB/BEAN + LAMBDA執行JUNIT /集成測試？

我在哪裏可以報告glassfish-embedded-all模塊相關的錯誤？我只發現玻璃魚服務器相關的傑拉。
