Okhttp: NoClassDefFoundError on API 23 when using coreLibraryDesugaring

[PhilippNowak96]

I recently updated to AGP 4.0 and wanted to activate coreLibraryDesugaring to benefit from it using java.time. Then I experienced a problem on an API 23 emulator (API 21 and 29 do not have this problem).

No pending exception expected: java.lang.NoClassDefFoundError: $r8$wrapper$java$util$Spliterator$-WRP

The crash occurs when executing
OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();

As soon as I remove coreLibraryDesugaringEnabled true from my build.gradle the problem is gone.

OkHttp versions tested: 4.6.0 and 4.7.2
Android version affected: API 23 (Android 6.0)
Android versions also tested but not affected: API 21 and API 29

Seems to be a problem on the AGP side: https://issuetracker.google.com/issues/157681341
