I have a junit test (integration test) with an embedded glassfish server. My test failed if I use lambda in my stateless ejb. Without lambda expression my test works fine.
Is there any fix or snapshot version of embedded glassfish server? I have not found any info about snapshot version of glassfish-embedded-all :(
Used dependency:
<dependency>
<groupId>org.glassfish.main.extras</groupId>
<artifactId>glassfish-embedded-all</artifactId>
<version>4.1.1</version>
<scope>test</scope>
</dependency>
If I uncomment the line (1) or (2) then the reference of my example bean is null in my junit test (lookup failed exception appears) :(
Bean/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;
}
}
Test class:
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());
}
}
Is there any embedded EE container for juint test + java 8 which is able to execute the java lambda expressions?
EDIT1: I have just created another test with lambda and classic iteration. Bean with classic iteration runs fine but with forEach i got a "Lookup failed" exception. What is going on here?
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: I can see an NCLS-DEPLOYMENT-00009 warning message in the maven log file. Only one related forum topic have found: Glassfish deploy error “Archive type of MyProject.jar was not recognized”. Here remove lambda expressions was suggested.

Is it a BUG?
Is there any working, embedded EE container to execute JUnit/Integration tests with Java8 + EJB/Bean + Lambda??
Where can I report glassfish-embedded-all module related bug? I only found glassfish server related jira.
The lambda bug is fixed a couple of days ago: https://github.com/payara/Payara/issues/647
