RE: [aspectj-users] Exposing state held in method annotations

Hmmm, strange. I tried the following, but apparently AspectJ is
unable to resolve the annotation interface type ConstantArguments:

   pointcut constantArgumentMethods() :
        call(@ConstantArguments * *.*(..));
    
    /*pointcut constantArgumentMethods(ConstantArguments annot) 
        : call(@ConstantArguments * *.*(..))
            && @annotation(annot);*/
    
    Object around(): constantArgumentMethods() {
        
        Signature sig =
            thisJoinPointStaticPart.getSignature();
        Class c = sig.getDeclaringType();
        MethodSignature msig =
            (MethodSignature)thisJoinPointStaticPart.getSignature();
        Method m = c.getMethod(sig.getName(),
msig.getParameterTypes());
        ConstantArguments = (ConstantArguments)
m.getAnnotation(ConstantArguments.class);

The last line here gives the error:

ConstantArguments cannot be resolved	ConstantArgumentsAspect.aj

And that, though the annotation type is located in the very same
package! Yet another bug?
