public final class JarLoader
extends java.net.URLClassLoader

Custom class loader for loading jar files. This class is needed because JDK does not offer a fine and easy way to delete open jars. The source code was taken from http://snipplr.com/view/24224/class-loader-which-close-opened-jar-files/ and slightly modified.
