ClassCastException org.dom4j.DocumentFactory for tests in Wildfly Swarm & Arquillian

Question

I have a problem with running EJB tests with Arquillian in Wildfly Swarm, it is related to Hibernate and this question: wildfly 10: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory

The error:

ERROR [stderr] (main) Caused by: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory"},"WFLYCTL0412: Required services that are not installed:" => ["jboss.persistenceunit.\"adaee1b1-6c6b-4f9b-834a-ea36333986b8.jar#AP\""],"WFLYCTL0180: Services with missing/unavailable dependencies" => undefined} ERROR [stderr] (main) at org.wildfly.swarm.container.runtime.RuntimeDeployer.deploy(RuntimeDeployer.java:273)

I am using Hibernate and JPA and solved this when running Wildfly Swarm by setting <scope>provided</scope> to all Hibernate depedencies. This doesn't work when runnings tests in Arquillian however.

ServiceTest.java

@RunWith(Arquillian.class)
public class ServiceTest {
    @EJB
    private TestService testService;

    @Deployment
    public static Archive<?> createDeployment() throws Exception {
        return new ArchiveBuilder().buildArchive();
    }

    @Test
    public void testService() {
        testService.test();
    }
}

ArchiveBuilder.java

public class ArchiveBuilder {
    public Archive<?> buildArchive() throws Exception {
        final JARArchive ejbArchive = ShrinkWrap.create(JARArchive.class);
        ejbArchive.addClass(AdapterService.class);

        final List<JavaArchive> artifacts = ArtifactLookup.get().allArtifacts(new String[]{"org.wildfly.swarm"});

        for (final JavaArchive javaArchive : artifacts) {
            ejbArchive.merge(javaArchive);
        }

        return ejbArchive;
    }
}

ArchiveBuilder is taken from this post: https://dzone.com/articles/testing-ejbs-with-swarm-and-arquillian

If I modify the Hibernate dependency to remove dom4j.dom4j:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.2.10.Final</version>

        </exclusion>
    </exclusions>
</dependency>

I get this instead:
