Why a Scala 2.13 app is trying to use `JavaClassValue` on Android if it is not available, then triggering `java.lang.NoClassDefFoundError`?

I'm running a Scala app on Android using https://github.com/dsvdsv/scala-android-plugin and Scala 2.13.8 and I get these weird stack traces on the logs:

They happen whenever some code path for some reason touches ClassValue or ClassTag -- which unfortunately happens more often than not inside my dependencies (I've removed everything from my own code and from the dependency usage I could, but that wasn't enough); but weirdly the app doesn't crash, it just runs fine (except it gets a little slow apparently when these errors happen).

Another weird thing is that it seems that it only triggers the error the first time it runs through these code paths (that touch ClassValue), then later the app goes through them many times and the error doesn't happen ever again.

If you look closely it will say it is using ClassValueCompat, which was introduced to fix the lack of java.ClassValue on Android among other things, but then it is not using the FallbackClassValue as it should, it is using JavaClassValue, which was supposed to not exist on Android and is in fact what is causing the error -- so it shouldn't be in use at all.

---

Notice that ClassValueCompat does this check to determine if it should use JavaClassValue or FallbackClassValue:

private val classValueAvailable: Boolean = try {
  Class.forName("java.lang.ClassValue", false, classOf[Object].getClassLoader)
  true
} catch {
  case _: ClassNotFoundException => false
}

I did this same check on my app initialization code and I got the ClassNotFoundException as expected.
