我有一个嵌入式glassfish服务器的junit测试（集成测试）。如果我在无状态ejb中使用lambda，我的测试失败了。没有lambda表达式，我的测试工作正常。
是否有嵌入式glassfish服务器的修复程序或快照版本？我还没有找到关于glassfish-embedded-all的快照版本的任何信息：（
使用的依赖：
<dependency>
<groupId>org.glassfish.main.extras</groupId>
<artifactId>glassfish-embedded-all</artifactId>
<version>4.1.1</version>
<scope>test</scope>
</dependency>
如果我取消注释第（1）行或第（2）行，那么我的例子bean的引用在我的junit测试中为空（出现查找失败的异常）:(
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;
}
}
测试类：
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());
}
}
是否有用于juint test + java 8的嵌入式EE容器能够执行java lambda表达式？
EDIT1： 我刚刚用lambda和经典迭代创建了另一个测试。经典迭代的Bean运行正常，但是对于每个我有一个“查找失败”异常。这是怎么回事？
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日志文件中看到NCLS-DEPLOYMENT-00009警告消息。只找到一个相关的论坛主题：Glassfish deploy error “Archive type of MyProject.jar was not recognized”。建议删除lambda表达式。

是BUG吗？
是否有任何可用的嵌入式EE容器用Java8 + EJB / Bean + Lambda执行JUnit / Integration测试？
我在哪里可以报告与glassfish嵌入的所有模块相关的错误？我只发现了玻璃鱼服务器相关的jira。
