Instead of compiling Java to Java bytecode which is then executed by the JVM (e.g. Hotspot), you compile it to native machine code/assembly + runtime (Substrate VM). However you loose the cross-platform ability and Java reflections won't work out of the box.

What's the GC performance of Substrate VM's GC? Is it still the 1G young 3G old thing?

What's the long term vision? In theory can this thing become "better" than HotSpot, JIT and G1/Z/Shenandoah?
