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.
