I run a simple test for an bean with openEjb. The test start but fails with a NullPointerException:

Thats the bean:

package com.example;

import javax.annotation.security.PermitAll;
import javax.ejb.Local;
import javax.ejb.Stateless;
import org.jboss.ejb3.annotation.SecurityDomain;
import com.example.client.ProjectManagerLocal;

@Stateless(name = "Example.ProjectManager")
@SecurityDomain("Example")
@Local(ProjectManagerLocal.class)
@PermitAll
public class ProjectManagerBean implements ProjectManagerLocal {
     public String createProject(String world) {
          return "Hello " + world;
     }
}

the interface:

package com.example.client;
 
public interface ProjectManagerLocal {
     String createProject(String world);
}

the test:

package com.example;

import javax.ejb.EJB;

import org.jboss.arquillian.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.spec.JavaArchive;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import com.example.ProjectManagerBean;
import com.example.client.ProjectManagerLocal;

@RunWith(Arquillian.class)
public class ProjectManagerBeanTest {

     @Deployment
     public static JavaArchive createTestArchive() {
          return ShrinkWrap.create(JavaArchive.class, "test.jar").addClasses(
               ProjectManagerBean.class, ProjectManagerLocal.class);
     }

     @EJB
     private ProjectManagerLocal projectManager;

     @Test
     public void testCreateProject() throws Exception {
          String text = projectManager.createProject("World!");
          Assert.assertEquals("fail", "Hello World!", text);
     }
}

If i change the version of the org.jboss.arquillian.container.arquillian-openejb-embedded-3.1 from 1.0.0-SNAPSHOT to 1.0.0.Alpha5 it works.

Version 1.0.0-SNAPSHOT
public void enrich(Object testCase) { if(SecurityActions.isClassPresent(ANNOTATION_NAME) && contextInst.get() != null) { injectClass(testCase); } }

Version 1.0.0.Alpha5 and actual GIT
public void enrich(Object testCase) { if(SecurityActions.isClassPresent(ANNOTATION_NAME)) { injectClass(testCase); } }

The field
{code}contextInst{code}
is null in 1.0.0-SNAPSHOT.
Is this a failure on my side or is it a bug in the actual 1.0.0-SNAPSHOT.

Thanks

1.0.0-SNAPSHOT is a very old version, you should try 1.0.0.CR5 of Arquillian Core and 1.0.0.CR2-SNAPSHOT of the openejb integration.

I would also recommend using Mavens DependencyManagement feature and use the Arquillian Core BOM

https://gist.github.com/1154075

That will let you set the Arquillian Core v and have Maven upgrade the Arquillian OpenEJB transitive dependencies to match the Arquillian Core v. specified.
