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))

for (Annotation candidate : annotated.getAnnotations())
{
if (beanManager.isStereotype(candidate.annotationType()))
{
for (Annotation stereotyped : beanManager.getStereotypeDefinition(candidate.annotationType()))
{
if (stereotyped.annotationType().equals(annotationType))

}
}
}
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(

)
@Retention(RUNTIME)
@Documented
public @interface GetYourHandlersHere {}

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

An open question is whether to support HandlesExceptions as a meta-annotation on any annotation, or just on a stereotype.

It turns out Solder already supports this, just not as a single method. Currently, the supported logic is:

if (AnnotationInspector.isAnnotationPresent(type, HandlesExceptions.class, false, bm) ||
AnnotationInspector.isAnnotationPresent(type, HandlesExceptions.class, true, bm)) {
...
}

The false means only look on the element (the type) and the true means only look for it on the stereotypes. I'll enhance Solder to have a more intuitive method.
