It seems that only one level of inheritance is taken into account. The problem is likely in Interceptors.flattenInterceptorBindings(BeanManagerImpl, Collection<Annotation>, boolean, boolean) or InterceptorBindingModel.

9.5. Interceptor resolution:
For a business method or EJB timeout method, the interceptor bindings include the interceptor bindings declared or inherited by the bean at the class level, including, recursively, interceptor bindings declared as meta-annotations of other interceptor bindings and stereotypes, together with all interceptor bindings declared at the method level, including, recursively, interceptor bindings declared as meta-annotations of other interceptor bindings.
