Examples of java.net.URLClassLoader$URLJarHandler

java.net.URLClassLoader
This class loader is responsible for loading classes and resources from a list of URLs which can refer to either directories or JAR files. Classes loaded by this {@code URLClassLoader} are granted permission to access theURLs contained in the URL search list.

         URL[] urls = new URL[clientJars.size()];
         for (int i = 0; i < clientJars.size(); i++)
         {
            urls[i] = clientJars.get(i);
         }
         URLClassLoader cl = new URLClassLoader(urls, parent);
         Thread.currentThread().setContextClassLoader(cl);
      }
      
    try {
      String testDelayStr=System.getProperty("test.delay","20000");
