jboss-as-arquillian-container-manager 7.1.1.Final not working with @Asynchronous

[m1ckey]

Hi, I am in the process of upgrading to JBoss AS 7.1.1.Final. It all works unless I add @Asynchronous to a production code bean called in the test. Without @Asynchronous it works.

With JBoss  AS 7.0.2.Final the test worked fine with or without the annotation. To be fair, I was only using web profile then.

When I deploy the app manually outside Arquillian it works.

What is really bizarre is that the error I'm getting has nothing to do with @Asynchronous, it cannot find a class that is definitely in the JAR. The class it cannot find is in a JAR that is not in the standard Maven repo and there is a warning about it when test executes.

Any ideas? Thanks!

Here's the bean:

@Stateless
@Asynchronous
@Local(LibraryImporter.class)
public class CacheAwareLibraryImporter implements LibraryImporter {

    @EJB
    private LibraryParser libraryParser;
    @EJB
    private LibraryService libraryService;
    @EJB
    private CacheableSongService cacheableSongService;
    @EJB
    private ApplicationConversation applicationConversation;

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void importLibrary(File libraryFile) {
        Library library = libraryService.createLibrary();
        applicationConversation.startConversation(library);

        cacheableSongService.initialise(library);
        libraryParser.process(libraryFile, library);
        cacheableSongService.finalise(library);

        applicationConversation.endConversation(library);
    }
}

I guess this is a known issue... ARQ-626.

Here's my workaround: http://blog.m1key.me/2012/09/arquillian-and-asynchronous.html

What's the error?

[aslak]

There is nothing broken with Async in Arquillian pr say. The problem you're facing is that when you call a Async method the execution in the TestClass continues (as defined by @Async, it's executed in a different Thread). If you don't wait for the Async method to finish 'somehow', Arquillian will finish the Test execution and undeploy the deployment. The NoClassDefFound error could come becasue the classes that is suppose to receive the Async call are now undeployed and no longer available in the container.

[m1ckey]

This could be right, because the tests that was actually working was parsing a significantly smaller file - so maybe undeployment has not happened yet. What is the proposed solution then?

[aslak]

You need to wait somehow..

This is a example using CDI to deploy special/alternative test Beans of the same type to handle around/invoke type latches on Async methods:

Hmm, yes. This is not ideal, but I can see what the problem is now. Thanks, Aslak!
