> When executing the following code on Geronimo server,
> =====================================================================
> ClassLoader loader = Thread.currentThread().getContextClassLoader();
> URL url = loader.getResource("javax/servlet/http/");
> JarURLConnection conn1 = (JarURLConnection) url.openConnection();
> conn1.setUseCaches(false);
> JarFile jarFile1 = conn1.getJarFile();
> JarURLConnection conn2 = (JarURLConnection) url.openConnection();
> conn2.setUseCaches(false);
> JarFile jarFile2 = conn2.getJarFile();
> System.out.println(jarFile1);
> System.out.println(jarFile2);
> =====================================================================
> there is a problem that "jarFile1" and "jarFile2" are same instances.
> Also, it is described in the javadoc of "useCaches" field as follows.
> "If false, the protocol must always try to get a fresh copy of the object."
> "org.apache.geronimo.kernel.classloader.JarFileUrlConnection" must return a different instance, when "useCaches" is false.
