/**
 * This stripped down URLClassLoader class is simply here to give us cross-platform support for code
 * that might need a valid classloader.
 *
 * 
 * If support is ever needed, we can implement a generator which will set the URLs of any
 * URLClassLoader to the jars and source paths used to compile GWT.
