Here are a couple problems:

* Figure out how to remove references to URLClassLoader from 
java.lang.ClassLoader.  URLClassLoader then refers to the URL related 
classes, these in turn refer to all of the URL protocol handlers.  The 
HTTPS protocol handler then refers to things in ...

* SecurityManager.  Need I say more?  The chain of classes needed by 
this class is unending.

The result is that the simplest 'Hello World' program that only calls 
System.out.println() requires many hundreds of classes that at first 
glance one might not think were necessary.
