Google never claimed that Android runs Java (after all, it does not, dex is not Java Bytecode and Dalvik/libART are not JVM). It never passed TCK and never claimed to.

They claimed that you can write Android apps in Java language, or reuse your existing libraries written in Java - like Google themselves did with Apache Commons.

On the contrary, J++ claimed to be Java implementation.

If APIs are going to be copyrightable, it will allow Oracle to hold all the third-parties using Java (or another JVM-based, like Kotlin or Scala) language hostage wrt where they can run their own software.

The end result is the same in terms of broken eco-system, anything is just word games.
