/**
 * River wide Service Provider Interface (SPI) to modify classloading behaviour.
 * 
 * Loosely based on the RMIClassLoaderSpi. To circumvent RMIClassLoaderSpi 
 * problems in some runtime environments, like Java Webstart and Netbeans platform api.
 * <p>
 * The default {@link RiverClassLoader.DefaultRiverClassLoaderSpi } delegates to the RMIClassLoader. 
 * <p>
 * To create a RiverClassLoaderSpi for netbeans, 
 * please look at: <a href='https://issues.apache.org/jira/browse/RIVER-336'>RIVER-336</a>
