/**
 * Wrapper for an embedded Jetty server serving the Skalli REST API.
 * <p>
 * The returned instance maps {@link RestletServlet} to the context path <tt>/api</tt>
 * and redirects all requests to {@link RestApplication} and the org.restlet engine.
 * <p>
 * The test should start the Jetty instance with {@link #start()}, e.g. in a
 * {@literal @BeforeClass} method, and ensure that it is stopped properly after
 * test execution, e.g. with an {@literal @AfterClass} method.
 * <p>
 * The server port can be configured with the system property <tt>PORT1</tt> (default: 8182).
