/**
 * {@link org.springframework.context.support.AbstractRefreshableApplicationContext}
 * subclass which implements the {@link ConfigurablePortletApplicationContext}
 * interface for portlet environments. Provides a "configLocations" property,
 * to be populated through the ConfigurablePortletApplicationContext interface
 * on portlet application startup.
 *
 * <p>This class is as easy to subclass as AbstractRefreshableApplicationContext:
 * All you need to implements is the {@link #loadBeanDefinitions} method;
 * see the superclass javadoc for details. Note that implementations are supposed
 * to load bean definitions from the files specified by the locations returned
 * by the {@link #getConfigLocations} method.
 *
 * <p>Interprets resource paths as servlet context resources, i.e. as paths beneath
 * the web application root. Absolute paths, e.g. for files outside the web app root,
 * can be accessed via "file:" URLs, as implemented by
 * {@link org.springframework.core.io.DefaultResourceLoader}.
 *
 * <p>This is the portlet context to be subclassed for a different bean definition format.
 * Such a context implementation can be specified as "contextClass" init-param
 * for FrameworkPortlet, replacing the default {@link XmlPortletApplicationContext}.
 * It will then automatically receive the "contextConfigLocation" init-param.
 *
 * <p>Note that Portlet-based context implementations are generally supposed
 * to configure themselves based on the configuration received through the
 * {@link ConfigurablePortletApplicationContext} interface. In contrast, a standalone
 * application context might allow for configuration in custom startup code
 * (for example, {@link org.springframework.context.support.GenericApplicationContext}).
