Issue details

OkHttp throws an SSLProtocolException, see stacktrace. Interesting is: It works with OkHttp 3.12.0, but crashes with 3.12.13

Reproduction steps/code

build.gradle:

    implementation("com.squareup.okhttp3:okhttp:3.12.13")
    implementation("com.squareup.okhttp3:okhttp-urlconnection:3.12.13")

            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .url("https://api-testnet.ergoplatform.com/")
                    .build();

            try (Response response = client.newCall(request).execute()) {
                response.body().string();
            } catch (IOException e) {
                e.printStackTrace();
            }

hi, in 3.12.9 they returned check for Build class to match simple android case. So a workaround is to add one as described here https://dkimitsa.github.io/2018/09/11/robovm-and-okhttp3-3-11-0/
