Thomas Diesler updated JBOSGI-305:
----------------------------------

    Description: 
Consider

      final boolean[] allGood = new boolean[2];
      ServiceFactory factory = new ServiceFactory()
      {
         @Override
         public Object getService(Bundle bundle, ServiceRegistration sreg)
         {
            ServiceReference sref = sreg.getReference();
            Bundle[] users = sref.getUsingBundles();
            assertNotNull("Users not null", users);
            assertEquals(1, users.length);
            assertEquals(bundle, users[0]);
            allGood[0] = true;
            return new Runnable()
            {
               public void run()
               {
               }
            };
         }

         @Override
         public void ungetService(Bundle bundle, ServiceRegistration sreg, Object service)
         {
            ServiceReference sref = sreg.getReference();
            Bundle[] users = sref.getUsingBundles();
            assertNotNull("Users not null", users);
            assertEquals(1, users.length);
            assertEquals(bundle, users[0]);
            allGood[1] = true;
         }
      };

Here we expect the service user to be the same in getService() and ungetService().
This works in Felix-2.0.4 but not in Equinox-3.5.2. In Equinox getUsingBundles() returns null in ungetService()

The Core TCK 4.2 expects the Felix behaviour in ServiceHookTests.testListenerHook03, AFAICS.
