Just to make it clearer:
* the interface I'm going to apply will remain the same during the whole program, and so I guess it can be loaded by a parent (even root) loader;
* the class to which the interface will be applied can change during the program execution, and so should be loaded by a custom classloader.

The actual hierarchy of the loaders is:

root (loads the interface to add)
  | \
  |  \
  |   custom_add (loads the class with the interface)
custom_remove (loads the class without the added interface)

So my question is: why the addition can work and the removal not? I mean, after the class has been reloaded by custom_add, I can cast the class to the added interface, while after reloading it with custom_remove I _can still_ cast it to the interface.
