没有第三方JVM支持的JikesRVM如何工作？

Question

I am new to JikesRVM. I get confused at first that how the RVM run by itself without a third-party VM support, given that the RVM is implemented by Java language.

Now I understand that the JikesRVM has a boot image runner which would load the data, code and rmap images into memory before passing control the the RVM. How do the images look like? It looks like they are machine code that can be directly executed. But what compiler generates the images, directly from Java language to machine code?

Thanks a lot in advance for any inputs.
