Java 7 (1.7) now that Android Studio 1.0 requires it?

I've got strange behavior in my Xamarin.Android app, and I suspect JDK 1.7 to be the problem.

I've installed Android Studio 1.0, which requires JDK 1.7 (and even the 64bit version). It would be great if Xamarin.Android could switch to JDK 1.7 instead of 1.6 now to stay in sync with other Android development tools.
