This is the behavior you'll get with your OkHttpClient if you don't specifically configure
`HandshakeCertificates`. Or you can do it explicitly with `addPlatformTrustedCertificates()`:

```java
HandshakeCertificates clientCertificates = new HandshakeCertificates.Builder()
    .addPlatformTrustedCertificates()
    .build();
OkHttpClient client = new OkHttpClient.Builder()

        throw TestAbortedException("Google Play Services not available", gpsnae)
      }

      val clientCertificates =
        HandshakeCertificates
          .Builder()
          .addPlatformTrustedCertificates()
          .addInsecureHost(server.hostName)
          .build()

      // Need fresh client to reset sslSocketFactoryOrNull
      client =
        OkHttpClient
          .Builder()

    builder = builder.heldCertificate(heldCertificate, heldCertificate.certificate)
    builder = builder.addTrustedCertificate(heldCertificate.certificate)
    builder = builder.addPlatformTrustedCertificates()
    val handshakeCertificates: HandshakeCertificates = builder.build()
  }

  @Test
  fun heldCertificate() {
    val heldCertificate: HeldCertificate = HeldCertificate.Builder().build()
