If you think ART is an AOT system, you might want to refresh your understanding of the system. ART has had a JIT for a long time now. Sure, HotSpot might have some features ART lacks, but ART has features that HotSpot lacks, so it's a wash. (And ART already has sub-millisecond GC pause times.) It's good and healthy for a language to have multiple implementations and there's no obligation whatsoever on the part of the Android people to switch to Oracle's JVM.
