[Dan Allen (JIRA)]

    [ https://jira.jboss.org/browse/SEAMCATCH-24?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568874#comment-12568874 ] 

Dan Allen commented on SEAMCATCH-24:
------------------------------------

Add this utility method to CatchExtension (should be pushed into Solder eventually)

public static <A extends Annotation> boolean isAnnotationPresent(Annotated annotated, final Class<A> annotationType, BeanManager beanManager)
   {
      if (annotated.isAnnotationPresent(annotationType))
      {
         return true;
      }
      
      for (Annotation candidate : annotated.getAnnotations())
      {
         if (beanManager.isStereotype(candidate.annotationType()))
         {
            for (Annotation stereotyped : beanManager.getStereotypeDefinition(candidate.annotationType()))
            {
               if (stereotyped.annotationType().equals(annotationType))
               {
                  return true;
               }
            }
         }
      }
      return false;
   }

Then replace the line that checks for HandlesExceptions

if (isAnnotationPresent(type, HandlesExceptions.class, bm))

Here are two classes to use for a test

@HandlesExceptions
@Stereotype
@Target({ TYPE })
@Retention(RUNTIME)
@Documented
public @interface GetYourHandlersHere {}

@GetYourHandlersHere
public class StereotypedExceptionHandler
{
   public void handlesAll(@Handles CaughtException<Throwable> caught)
   {
   }
}

> The HandlesExceptions should be permitted on a stereotype so annotations can be consolidated.
