Try printing CoreFactoryImpl.class.getClassLoader() within your bundle
using the service tracker and then print cso.getClass().getClassLoader()
from the service object and see if they are coming from the same class
loader.
One thing that seems weird to me, why are you casting to CoreFactoryImpl
instead of CoreFactory?

For the life of me I can't see why this fails. Here's the runup in
detail:
coreTracker is a ServiceTracker for CoreServiceImpl, defined in a
bundle I'm trying to access from the integration test bundle. These
are the relevant declarations:
public interface CoreFactory extends ServiceFactory
public class CoreFactoryImpl implements CoreFactory
Integration test uses a ServiceTracker (CoreTracker) to locate the
sole core instance from the core bundle like this:
Object cso = coreTracker.getService();
System.out.println("cso:"+cso);
> cso:com.gestalt.soakit.core.internals.corefactoryi...@dead19
So why should this cast fails with a ClassCastException?
CoreFactoryImpl cs = (CoreFactoryImpl)cso;
I'm going blind from staring at this. Maybe someone can spot what I'm
missing. Here's some more detail.
Class csoClass = cso.getClass();
System.out.println("csoClass:"+csoClass);
> csoClass:com.gestalt.soakit.core.internals.CoreFactoryImpl
Class[] csoClasses = csoClass.getClasses();
System.out.println("cso.getClasses():"+csoClass.getClasses());
> cso.getClasses():[Ljava.lang.Class;@1cc5ef
Class[] csoInterfaces = csoClass.getInterfaces();
System.out.println("cso.getInterfaces():"+csoClass.getInterfaces());
> cso.getInterfaces():[Ljava.lang.Class;@c44af4
