  /**
   * In OkHttp 4.5 and earlier, HTTP 307 and 308 redirects were only honored if the request method
   * was GET or HEAD.
   *

 *  Fix: Un-deprecate `MockResponse.setHeaders()` and other setters. These were deprecated in OkHttp
    4.0 but that broke method chaining for Java callers.

 *  Fix: Don't crash on HTTP/2 HEAD requests when the `Content-Length` header is present but is not
    consistent with the length of the response body.

 *  Fix: Don't crash when converting a `HttpUrl` instance with an unresolvable hostname to a URI.
