Well, ConverterTest is not annotated with a bean defining annotation/scope annotation, so if a trimmed bean archive is used ConverterTest is not recognized as a bean and no ProcessInjectionPoint is fired - this is excpected from CDI POV. Arquillian CDI test enricher most probably ignores trimmed bean archives (probably even bean-discovery-mode=annotated) and simply attempts to inject any @Inject field in a test class.
