StructureMap: how to replace an object at runtime

Question

I am trying to inject a laughed instance of ISession (NHibernate) into a structural map. Currently, all this is related to the Bootstrap method, but I want to replace the one that is being mocked. I tried EjectAllInstancesOf, but it threw execption.

 [TestFixtureSetUp]
        public void TestFixtureSetup()
        {
            Bootstrapper.Bootstrap();
           //TODO: need to remove already wired up types that we are mocking.
            var mockSession = MockRepository.GenerateStub<ISession>();
            var mockLoggerFactory = MockRepository.GenerateStub<ILoggerFactory>();

            ObjectFactory.EjectAllInstancesOf<ISession>();
            ObjectFactory.EjectAllInstancesOf<ILoggerFactory>();

            ObjectFactory.Inject<ISession>(mockSession);
            ObjectFactory.Inject<ILoggerFactory>(mockLoggerFactory);
        }

Error:

System.NullReferenceException: ​​ .
