I bet that when Java 10 finally gets released, maybe around 5 years from now, Google might eventually release Java 8 support.

Even their recent actions with OpenJDK are related to version 7, not 8.

At their Autumn conference they only addressed Java 8, reluctantly during Q&A, and still asked devs to cherry pick features from it.

Given that Google is creating a Python 3 / Python 2 situation, due to their Java fork, I fail to see how their actions are less damaging to the Java eco-system than what Microsoft did.
