## Architecture

### Module Structure

    crashed.

 *  Fix: Avoid `InetAddress.getCanonicalHostName()` in MockWebServer. This avoids problems if the
    host machine's IP address has additional DNS registrations.

 *  New: Create a JPMS-compatible artifact for `JavaNetCookieJar`. Previously, multiple OkHttp
    artifacts defined classes in the `okhttp3` package, but this is forbidden by the Java module
