It seems like dx can be convinced to accept 1.7 code [1] and almost everything needed API-wise to support the new Java7 language features is already in Android 4.0+ [2] (and thus also in RoboVM which is currently based on 4.1). So if jfx78 can be made to compile with robovm-rt.jar or a modified android.jar (which doesn't hide the Java7 classes like AutoCloseable) on the bootclasspath we should have a version of jfx that can run on Android and Dalvik.
