"no such provider: BCJSSE" when using Robolectric after upgrading to OkHttp 4.7.0 or later

I have some tests which use OkHttp to verify some server call results and are run using the RobolectricTestRunner.

After upgrading the OkHttp library from version 4.6.0 to anything above it, I am unable to instantiate an OkHttpClient, which fails with the following error:

java.security.NoSuchProviderException: no such provider: BCJSSE

I have read through OkHttp's Changelog but cannot find any mention of changes related to Bouncycastle, which I suspect has to do with the crash, or anything else that seems related to this issue.

When running the test as a Junit4 test, instead of the RobolectricTestRunner, everything works fine, but I rely on robolectric providing functionality for my actual tests that cannot easily be mocked, so I have to keep using it.

I am using

• Robolectric 4.3.1
• Android Studio 4.
• Android Gradle Plugin 3.5.0

What is the reason for the crash when updating the OkHttp dependency? And what can be done to solve this issue?

Smallest code snippet to replicate the issue:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;

import okhttp3.OkHttpClient;

@RunWith( RobolectricTestRunner.class )
public class TestClass {

  @Test
  public void test() {
    OkHttpClient okHttpClient = new OkHttpClient().newBuilder().build();

    //do the actual teststuff
  }
}

Stacktrace:

java.security.NoSuchProviderException: no such provider: BCJSSE
