ResourceBundleControlProvider (Java SE 12 & JDK 12 )

```
public interface ResourceBundleControlProvider
```
An interface for service providers that provide implementations of ResourceBundle.Control. The default resource bundle loading behavior of the ResourceBundle.getBundle factory methods that take no ResourceBundle.Control instance can be modified with ResourceBundleControlProvider implementations.
Provider implementations are loaded from the application's class path using ServiceLoader at the first invocation of the ResourceBundle.getBundle factory method that takes no ResourceBundle.Control instance.
All ResourceBundleControlProviders are ignored in named modules.

Since:

1.8
