I'm creating integration tests for a JAX-RS/Jersey Webservice deployed on Tomcat 8 using arquillian.

I am trying to do a POST request like that:

E dummy = dummyFactory.manufacturePojo(getSubClassType());
dummy.setId(null);

Client client = ClientBuilder.newClient();
WebTarget target = client.target(BASE_URI).path("bandeira");

Response response = target.request(MediaType.APPLICATION_JSON)
            .header(HttpHeaders.AUTHORIZATION, CHAVE_TESTE)
            .header(HttpHeaders.CONTENT_TYPE, "application/json")
            .post(Entity.entity(dummy, MediaType.APPLICATION_JSON));

When I do that I get this exception:

Caused by: java.lang.IllegalStateException: Already connected

I could use some heuristic since I am still learning arquillian and Jersey client API :) Thank you

It may be that java.lang.IllegalStateException: Already connected only masks the SSLHandshakeException. Please take a look at the issue #3000 (previously known as JERSEY-2728 bug).
