Looking at the JIT, I pretty much have to completely strip it down into nothing because most of the classes in there, would be removed anyway. As such, the classes would be made simplified. Really the only thing to keep is the exceptions and the stack caching handler along with some other operations. The JIT itself would be given the entire class layout, and every system would use a similar space to represent the executable.

Perhaps for the auto-interpreter, it could either integrate with the JIT or it can become an emulator of sorts for a given target and emulate some hardware. However that would require a working JIT and such. But that is a good potential idea in the future, have the interpreter now be an intermediary that will in the future turn into the emulator that uses the Java SE Host or potentially Java ME. I suppose for simplicity that I can model the instruction format that the interpreter executes and have it use MIPS or an existing instruction set. This would allow me to write the JIT as it would be a normal system. Then whatever happens in the machine code will change what happens on the interpreted system. So this way, methods are just slices of some architecture which is then executed. Then once I have basic Hello World stuff, I can then work on a primitive systems emulator which I can use to run existing programs on (in a limited fashion) along with allowing a testable and somewhat hosted SquirrelJME environment.

Yes, this can work. Once an ExecutableClass I can then serialize it to an output stream for cache purposes. For most systems there will be just a single class that can hold machine code and other class details.

I learned that Java ME 8 does not have StackOverflowException, so this means if this occurs it will have to be something else.
