##### OkHttp no longer uses the default SSL context.

Applications that want to use the global SSL context with OkHttp should configure their
OkHttpClient instances with the following:

```java
okHttpClient.setSslSocketFactory(HttpsURLConnection.getDefaultSSLSocketFactory());
```

A simpler solution is to avoid the shared default SSL socket factory. Instead, if you
need to customize SSL, do so for your specific OkHttpClient instance only.

    server.enqueue(MockResponse().setBody("abc"))
    val url = server.url("/")
    val connection = url.toUrl().openConnection() as HttpsURLConnection
    connection.setSSLSocketFactory(handshakeCertificates.sslSocketFactory())
    connection.setHostnameVerifier(RecordingHostnameVerifier())
    assertThat(connection.getResponseCode()).isEqualTo(HttpURLConnection.HTTP_OK)

        if (sslSocketFactory != null && connection instanceof HttpsURLConnection) {
            ((HttpsURLConnection) connection).setSSLSocketFactory(sslSocketFactory);
        }
        return connection;
    }

    public void execute(final Consumer<CurlResponse> actionListener, final Consumer<Exception> exceptionListener) {
        connect(con -> {

            if ( hv != null ) {
                ( (HttpsURLConnection) this.connection ).setHostnameVerifier(hv);
            }
            if ( ssf != null ) {
                ( (HttpsURLConnection) this.connection ).setSSLSocketFactory(ssf);
            }
        }

        this.connection.setRequestMethod(this.method);
        this.headerFields = null;

        this.cookieDatePatterns = cookieDatePatterns;
    }

    public void setDnsResolver(final DnsResolver dnsResolver) {
        this.dnsResolver = dnsResolver;
    }

    public void setSslSocketFactory(final LayeredConnectionSocketFactory sslSocketFactory) {
        this.sslSocketFactory = sslSocketFactory;
    }
