Subtle difference - extending ListResourceBundle vs ResourceBundle

I've been mucking about extending ListResourceBundle and then just plain ResourceBundle trying to get things to work with a base case - a custom resource bundle.

Taking a look at the Java i18n tutorial, extending ListResourceBundle doesn't require subclassing the default bundle; see here.

Then taking a look at the ResourceBundle javadocs and their custom resource bundle example, you *do* have to extend the default bundle; see here.


public class MyListResources_it extends ListResourceBundle {

as opposed to:

public class MyResources_it extends MyResources {

Kind of a confusing inconsistency - maybe the ListResourceBundle is just smarter about its look up.
