Okay so the wrong value was getting pushed or loaded, but it is in a
constructor which takes a `long` argument so I believe that the top
of types has not be handled.

## 8:58

And that works now.

## 9:57

So the full frame is wrong with there is a long/double, it is missing a
top so I suppose that is very much implied perhaps.

## 9:59

Okay so, the top is just implied in the local variable info. So that is
fun.

I had an idea. For native instructions and such I really do want to keep
it in Java code or at least have something very close. So what I can do is,
when I write my own Java assembler I can have `impdep1` be used for these
things. Since this instruction is reserved I can just use it and the class
dumper should be fine with it. Since I cannot encode any information into
it and it would actually be quite complicated, I can have an extra attribute
in the byte code which contains the meaning for every one of those
instructions. So when my assembler reaches a special native assembly kind of
thing it will just pretty much do the thing with it. I will just have this
assembler and the compiler itself which will be for everything related to the
Java language. It will pretty much be the same tool really.

I also thought the progression of VMs:

 * _SpringCoat_ -- Initial pure interpreter, what I am building now.
 * _SummerCoat_ -- Register based machine with some optimizations as needed.
 * _AutumnCoat_ -- A fake raw instruction kind of like native machines.
 * _WinterCoat_ -- The final implementation that SquirrelJME will use.

Also, I thought instead of MIDlets, I will just have a basic hello world kind
of thing. That is simple and shows things off nicely.

## 12:32

Now I just really want a basic demo that does the one thing.

Note sure how I want to handle `Reference` and such.
