Richard S. Hall resolved FELIX-1131.
------------------------------------

    Resolution: Invalid
      Assignee: Richard S. Hall

I am closing this for now. I think the current behavior is correct as far as the spec is concerned.

>             Project: Felix
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: felix-1.6.0

>  * bundle A defines an interface R and a class S in different packages, whith S implementing R
>  * bundle B defines a class T extending S, it has an import statement on S package, but not on R package
>  * bundle C defines a ServiceFactory that export T service without any import on any package from R, S, T
> in this case, the line 426 of ServiceRegistrationImpl is executed:
>                        allow = getServiceRegistration().isClassAccessible(requestClass);
> which looks like:
>    protected boolean isClassAccessible(Class clazz)
>    {
>        try
>        {
>            // Try to load from the service object or service factory class.
>            Class sourceClass = (m_factory != null)
>                ? m_factory.getClass() : m_svcObj.getClass();
>            Class targetClass = Util.loadClassUsingClass(sourceClass, clazz.getName());
>            return (targetClass == clazz);
>        }
>        catch (Exception ex)
>        {
>            // Ignore this and return false.
>        }
>        return false;
>    }
> So felix checks if the classloader used to load the factory can also load the interface, which is not the case in my example.
> So isClassAccessible returns false and the event is not dispatched to the service listener.
