Reading the doc, you guys specify that this will only work if the methods
intercepted are public. I would suggest, for Guice, to provide a Method
interceptor matcher that matches only public methods so that people don't
make the mistake intercpeting package-private methods....

Something like:
public static Matcher<AnnotatedElement>
publicMethodAnnotatedWith(final Class<? extends Annotation>
annotationType) {
               return new AnnotatedWithType(annotationType){
                       public boolean matches(AnnotatedElement element) {
                               boolean v=
element.getAnnotation(annotationType) != null;
                               if (!v)return v;
                               if (!(element instanceof Method)){
                                       return false;
                               }else{
                                       Method method=(Method)element;
                                      
v=Modifier.isPublic(method.getModifiers());
                                       if (!v){
                                               log.error("Method is not
public, will not intercept");
                                       }
                                       return v;
                               }

                       }
               };
       }
