### AndroidX Test and Android OS Versions
androidx.test:core:1.5.0
androidx.test:orchestrator:1.4.1
Emulator: Android 30 Google API.

### Link to a public git repo demonstrating the problem:

Start by reproducing the intermittent failure on the Android 30 Google API emulator using androidx.test:core:1.5.0 and androidx.test:orchestrator:1.4.1, then compare it with the versions reported as stable. Trace the failure from ActivityScenario through ServiceLoaderWrapper and the missing jar in the log. Done means the tests no longer fail because auxiliary jar files are unavailable.
