Use Jersey's Apache HTTP client handler instead of default one for the REST API tests

Added: CloseableClientResponse JerseyClientHelper BaseTest#getServiceFor(String username, String password) BaseTest#getServiceFor(String resource, String username, String password) The Apache implementation is stricter than the JDK implementation previously used: any time you obtain a ClientResponse from Jersey it needs to be closed otherwise connections might leak. Therefore all the BaseTest#getResponse methods now return a CloseableClientResponse that implements AutoCloseable, and the right pattern to use in the tests is: try (CloseableClientResponse response = getResponse(RequestType.GET, "id/" + note.getId())) { // Do something with the response assertEquals(Response.Status.OK.getStatusCode(), response.getStatus()); assertEntityEqualsDoc(response.getEntityInputStream(), note); } This is true no matter what signature of getResponse you are using and whatever HTTP method you are invoking: POST, GET, PUT, DELETE. If you are not relying on BaseTest#getResponse but are using directly WebResource.get or WebResource.post to make a call then you must do something like: WebResource wr = client.resource(NUXEO_URL).path(path); try (CloseableClientResponse cr = CloseableClientResponse.of( wr.queryParam( "access_token" , accessToken).get(ClientResponse.class))) { assertEquals(401, cr.getStatus()); } If you are not extending BaseTest and are instantiating a Client yourself, you must make sure to rely on the Apache HTTP client by calling: Client client = JerseyClientHelper.DEFAULT_CLIENT; or: Client client = JerseyClientHelper.clientBuilder() .setXXX() .setYYY() .build();
