OkHttp 4.3.1 didn't find class "org.conscrypt.ConscryptHostnameVerifier" on path

okhttp-4.3.1-log-spam.md

OkHttp 4.3.1 emits log spam on Android, even when using it in trivial way.

Example code:

Disposable disposable = Single.fromCallable(() ->
    new OkHttpClient().newCall(new Request.Builder()
        .url("https://raw.githubusercontent.com/square/okhttp/master/README.md")
        .get()
        .build())
    .execute()
    .body()
    .string()
)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(
    textView::setText,
    failure -> textView.setText(Log.getStackTraceString(failure))
);

This emits:
