ContextClassExporter.java
This is a ClassExporter that exports any classes found in the context
of the specified class loader. You can create your own classloader
that will find the classes that will be exported, or--in its simplest
use--don't specify *any* class loader. This will cause the
ContextClassExporter to use the current context class loader.
WARNING: using the current context class loader will allow clients
to download *any* class accessible on the classpath of your application.
For debugging this is fine, but if you're concerned about revealing
details of your implementation, then this may not be a good idea.
