  * <h2>Supported Jetty Versions</h2>
  * <p>
- *     This {@code RequestLogImpl} only supports Jetty 7.0.0 through Jetty 10.
- *     If you are using Jetty 11 with the new Jakarta Servlets (namespace {@code jakarta.servlet})
- *     then you will need a more modern version of {@code logback-access}.

  * <h2>Configuring for Jetty 9.4.x through to Jetty 10.0.x</h2>
  * <p>
- *     Jetty 9.4.x and Jetty 10.x use a modern @{code server.setRequestLog(RequestLog)} interface that
- *     is based on a Server level RequestLog behavior.  This means all requests are logged,
- *     even bad requests, and context-less requests.  The internals of the Jetty Request and
- *     Response objects track the state of the object at the time they are committed (the
- *     actual state during the application when an action on the network commits the
- *     request/response exchange).  This prevents behaviors from 3rd party libraries
- *     that change the state of the request / response before the RequestLog gets a chance
- *     to log the details.  This differs from Jetty 9.3.x and
- *     older in that those versions used a (now deprecated) {@code RequestLogHandler} and
- *     would never see bad requests, or context-less requests,
- *     and if a 3rd party library modifies the the response (for example by setting
- *     {@code response.setStatus(200)} after the response has been initiated on the network)
- *     this change in status would be logged, instead of the actual status that was sent.
