What are the schemes for creating a new class and using it from within a
running java application?  What is a good way to save the state of all
instances of a class?

I can think of one way to create new classes from a running java application.
        1. write a $class.java
        2. use a system call to compile it to $class.class
        3. read $class.class into newclass (???)
        4. defineClass, etc.
        5. use it as if it had been in the application's original compile

If I make changes to $class.java and re-create it, will things still work?

How can I save an instance to disk?
Is it possible to look at an instance's class instance an determine the
area of memory it occupies or the list of attributes?
