----------------------------------

             Summary: @specializes @alternative child class disables super class even when not enabled when using stereotypes
                 Key: OWB-737
                 URL: https://issues.apache.org/jira/browse/OWB-737
             Project: OpenWebBeans
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.6
         Environment: OS X 10.7.5 / Tomcat 7.0.22; Windows 7 / IBM WebSphere Application Server 7.x;
            Reporter: Teemu Andersén
            Priority: Minor


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);
}
