This required the Kotlin DSL to add special integration to work with Groovy closures.
This has also forced plugins written in languages other than Groovy to use Groovy types for some APIs.

When the Kotlin DSL was introduced, we made an effort to add non-Groovy equivalents for all APIs.
This has been mostly done, but there remain a few holdouts (fixing these is out of scope).

    This regression was introduced in OkHttp 4.3.0.
 *  Fix: Don't crash with an `IllegalArgumentException` when using custom trust managers on
    Android 10. Android uses reflection to look up a magic `checkServerTrusted()` method and we
    didn't have it.
 *  Fix: Explicitly specify the remote server name when making HTTPS connections on Android 5. In
