Java EJB JNDI Beans Lookup Failed

The above is a pom that is the parent of the below modules:

I have some stateless beans such as:

@Stateless
@Local
public class ProcessorBean implements Processor {
     // implemented methods
}

I am using an embedded EJBContainer for Glassfish for unit tests. When accessing them using the following:

Processor processor = (Processor) container.getContext().lookup(new String("java:global/classes/ProcessorBean!com.screening.processor.Processor");

It works correctly. The issue is that when I include Module 2 as part of Module 1 the unit tests fail by throwing the following Exception:

Having a look at the classes Apache Maven does generate this. I am not sure how to fix this. This only happens once I include Module 2 as part of Module 1.

Any ideas?
