Jersey: Print the actual request

Question

How can I view the actual request that Jersey generates and sends to the server? I am having issues with a particular request and the fellow running the webserver asked to

Since Jersey 2.23, there's a LoggingFeature you could use. The following is a bit simplified example, please note that you can register the feature on WebTarget as well.

Logger logger = Logger.getLogger(getClass().getName());

Feature feature = new LoggingFeature(logger, Level.INFO, null, null);

Client client = ClientBuilder.newBuilder()
        .register(feature)
        .build();

Response response = client.target("https://www.google.com")
        .queryParam("q", "Hello, World!")
        .request().get();

JavaDoc of LoggingFeature says that the request "and/or" the response is logged lol. On my machine, both are logged.
