assert does not match the correct result code

I have a very simple test that is failing, maybe you can try it and reproduce the error in your pc?
this is the test:

@RunWith(HttpJUnitRunner.class)
public class TestMy{
@Rule
public com.eclipsesource.restfuse.Destination destination = this.getDestination()

```
@Context
private Response response;

@HttpTest(
method = Method.POST,
path = "/create",
content = USER1,
order = 200
)
public void testRegistrationUser1()
{
assertCreated(response);
}

@HttpTest(
method = Method.POST,
path = "/create",
content = USER1,
order = 210
)
public void testRegistrationUser1Again()
{
assertConflict(response);
}
```

-I am running this in jetty.
-in the second test I get a 409 back but the assertion fails.
-I tried this same thing (creating a user and then trying to create it again) with apache's httpclient and indeed I get a 409 back.

so it seems in some cases even though you get the correct code back the framework doesn't direct it through the right path.
regards.
