Yes, this might be true for the static backend. However, the JIT integration would be extremely painful. To handle, let's say, the exceptions you get from C++, you'd need to write custom assembler that depends on the C++ compiler you used, full of non-standard binary data like the "eh" sections produced by gcc. Similarly, there is no standard way at all (as far as I know) to learn how to build a new object from scratch (like get its vtable pointer and know where it must be stored). You might start by learning how they manage to do that in other VMs (like the various JVM), but my guess is that although they are using C++ to write the VM, all Java-level objects are implemented by controlling the exact layout of memory, not as C++ objects at all.
