/**
 * This is a customization of {@link BrandingPlugin} for GlassFish.
 *
 * If a properties file META-INF/webconsole.properties is available
 * through the class loader of this class, the properties overwrite the default
 * settings according to the property names listed in {@link BrandingPlugin}.
 * The easiest way to add such a properties file is to provide a fragment bundle with the file.
