Description

When aaj creates a journal class for a model, it doesn't send unloadable, but the parent Journal class does. When running in development (config.cache_classes = false) the journal subclass doesn't reload with the parent, so it loses the overridden <=> method and picks up the implementation in Comparable. That in turn screws up the check in one of the save hooks and an exception is raised a little further down the line.

I have no idea why it seems to work as-is for core journaled models. I also don't know how to test it, because the test env (and script/console) don't seem to reload the classes in the same way.

To replicate, create a plugin with a journalized model and a controller action that saves an instance of that model. The reset_instance_variables save hook will raise an exception.
