Implementation of review comments for classpath and jar

resourceFactories
I had to add this class file for JarResourceFactory separately although the logic lies entirely in ClasspathResourceFactory. The reason is I cannot put two schemes that can be handled by a factory class. So ClasspathResourceFactory has scheme as classpath and JarResourceFactory has scheme as jar. If we can put comma separated values as scheme for resource factories, we need additional code change in newResource(URI uri) method in AbstractAggregatorImpl to handle it. Please suggest.
