Guillaume Nodet commented on FELIX-1131:
----------------------------------------
Well, my understanding of "if no source if found then returns true" is not
really ambiguous.
IIUC, this is the case when no provider wire is found, so we should just return
true.
> ServiceReference.isAssignableTo fails when using a factory that can not see
> the exported class and the bundle exporting the service does not have a
> direct wire to this class

> Key: FELIX-1131
> URL: https://issues.apache.org/jira/browse/FELIX-1131
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: felix-1.6.0
> Reporter: Guillaume Nodet
>
> * 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.
