Cannot run tests with jetty7 embedded profile

When trying to run a test where a simple servlet is deployed, I get the following exception:

The test is:

public class SimpleTest extends Arquillian {
@Deployment
public static WebArchive createDeployment()

{ return ShrinkWrap.create(WebArchive.class, "simpletest.war") .addWebResource("WEB-INF/web.xml", ArchivePaths.create("web.xml")); }

@Test
public void shouldBeAbleToCallServlet() throws Exception

{ String body = new RichStream(new URL("http://localhost:8080/simpletest").openStream()).asString(); Assert.assertEquals( "Verify that the servlet was deployed and returns the expected result", "hello", body); }

}
