 *  Fix: Don't leak connections when using ALPN on the desktop.
 *  Fix: Update Jetty ALPN to `7.1.2.v20141202` (Java 7) and `8.1.2.v20141202` (Java 8).
    This fixes a bug in resumed TLS sessions where the wrong protocol could be
    selected.
 *  Fix: Don't crash in SPDY and HTTP/2 when disconnecting before connecting.
 *  Fix: Avoid a reverse DNS-lookup for a numeric proxy address
 *  Fix: Resurrect http/2 frame logging.
