> The root cause is in the following code of RegionCoprocessorHost:
> {code}
> for (Class<?> c : implClass.getInterfaces()) {
> if (CoprocessorService.class.isAssignableFrom(c)) {
> region.registerService( ((CoprocessorService)instance).getService() );
> }
> }
> {code}
> We currently only check the interfaces directly implemented by the underlying
> class.
> What should be done is to check all the interfaces implemented by class
> itself and its superclasses.
