EVALUATION

Added a private method into URLClassLoader which takes an extra boolean argument for caller to indicate whether to do class bytes verification when loading the class. In addition, enhanced all the classloader classes along the classloader hierarchy with similar private methods in order to pass this extra argument to java.lang.ClassLoader class and eventually down to JVM.
