> When using stereotypes to select alternatives the OWB doesn't recognize a Bean as an alternative when it processes specialized classes. This causes the super class to be always disabled.
> Not sure if this is a bug or not but in most other cases the same class would be recognized as an alternative even if it was marked as one via stereotype and not directly using the @Alternative annotation.
> Steps to reproduce:
> 1) create a test alternative stereotype
> 2) create a service
> 3) create an alternative test service
>     - extend the production service
>     - annotate with test alternative stereotype and specializes
> 4) Don't enable the test alternative stereotype
> Expected:
> The production service is enabled
> What happens:
> Both services are disabled
> Example (had an example program but didn't know where to submit it):
> @Stereotype
> @Alternative
> @Retention(RetentionPolicy.RUNTIME)
> @Target({ METHOD, FIELD, PARAMETER, TYPE })
> public @interface Development {
> }
> public class ServiceBean implements Serializable {
> 	public String getMessage() {
> 		return "Production";
> 	}
> }
> /**
>  * Alternative implementation that is enabled by Development stereotype.
>  */
> // @Alternative - When this annotation is commented this class is not recognized as an alternative when processing specialized classes.
> @Development
> @Specializes
> public class DevelopmentService extends Service {
> 	@Override
> 	public String getMessage() {
> 		return "Development";
> 	}
> }

> Problem area:
> org.apache.webbeans.util.WebBeansUtil [1477-1486]:
> if (!AnnotationUtil.hasClassAnnotation(specializedClass, Alternative.class))
> {
>     //disable superbean if the current bean is not an alternative
>     ((AbstractOwbBean<?>)superBean).setEnabled(false);
> }
> else if(altManager.isClassAlternative(specializedClass))
> {
>     //disable superbean if the current bean is an enabled alternative
>     ((AbstractOwbBean<?>)superBean).setEnabled(false);
> }
