/**
 * {@code AbstractResourceBundleProvider} is an abstract class that provides
 * the basic support for a provider implementation class for
 * {@link ResourceBundleProvider}.
 *
 * <p>
 * Resource bundles can be packaged in one or more
 * named modules, <em>service provider modules</em>.  The <em>consumer</em> of the
 * resource bundle is the one calling {@link ResourceBundle#getBundle(String)}.
 * In order for the consumer module to load a resource bundle
 * "{@code com.example.app.MyResources}" provided by another module,
 * it will use the {@linkplain java.util.ServiceLoader service loader}
 * mechanism.  A service interface named "{@code com.example.app.spi.MyResourcesProvider}"
 * must be defined and a <em>service provider module</em> will provide an
 * implementation class of "{@code com.example.app.spi.MyResourcesProvider}"
 * as follows:
 *
 * <blockquote><pre>
 * {@code import com.example.app.spi.MyResourcesProvider;
 * class MyResourcesProviderImpl extends AbstractResourceBundleProvider
 *     implements MyResourcesProvider
 * {
 *     public MyResourcesProviderImpl() {
 *         super("java.properties");
 *     }
 *     // this provider maps the resource bundle to per-language package
 *     protected String toBundleName(String baseName, Locale locale) {
 *         return "p." + locale.getLanguage() + "." + baseName;
 *     }
 *
 *     public ResourceBundle getBundle(String baseName, Locale locale) {
 *         // this module only provides bundles in French
 *         if (locale.equals(Locale.FRENCH)) {
 *              return super.getBundle(baseName, locale);
 *         }
 *         // otherwise return null
 *         return null;
 *     }
 * }}</pre></blockquote>
 *
 * Refer to {@link ResourceBundleProvider} for details.

     * the resource bundle name of {@code "p.resources.Bundle"} of
