 * `java.net.URL` it's possible to create an awkward URL like `http:/` with scheme and path but no
 * hostname. Building APIs that consume such malformed values is difficult!
 *
 * This class has a modern API. It avoids punitive checked exceptions: [toHttpUrl] throws
 * [IllegalArgumentException] on invalid input or [toHttpUrlOrNull] returns null if the input is an

    to detect the host platform and got confused because Robolectric looks like
    Android but isn’t!
 *  Fix: Change `CertificatePinner` to skip sanitizing the certificate chain
    when no certificates were pinned. This avoids an SSL failure in insecure
    “trust everyone” configurations, such as when talking to a development
    HTTPS server that has a self-signed certificate.
