you can reasonably do so i.e. if it takes a whole page of code to set
      up an example, then Javadoc probably isn't the right place for it.
      Longer or more elaborate examples are probably better suited
      to the package docs.
   9. Test methods are a good place to add Javadoc, because you can use it
      to succinctly describe e.g. preconditions, actions and expectations

 *  **OkHttp now supports prior knowledge cleartext HTTP/2.** Enable this by setting
    `Protocol.H2_PRIOR_KNOWLEDGE` as the lone protocol on an `OkHttpClient.Builder`. This mode
    only supports `http:` URLs and is best suited in closed environments where HTTPS is
    inappropriate.

 *  New: `HttpUrl.get(String)` is an alternative to `HttpUrl.parse(String)` that throws an exception

 * This is particularly the case for <code>Object get<i>Classname</i>Key( <i>Classname</i> <i>classname</i> )</code>
 * method, which by default return the object itself and is expected to be overridden to calculate better suited key
 * value.
