Google did such a good job implementating Java that to this day there are still compatibility issues with standard Java, the library is incomplete and not all features of a standard JVM are available in ART.

They just broke Java the same way as Microsoft tried first, but since its the "Do no evil" company it gets a free pass.

Had it been other company and the Google support team would have another opinion.

I care about companies that care about Java, not those that fork the eco-system.

There are several companies playing by the rules, selling JVM implementations since the Sun days, none of them ever had issues either with Sun or Oracle.
