Java generic based on erasure, so only Object are available at runtime

gistfile1.java

class Father {}
class Child extends Father {}

public class Test {
	public static void main(String args[]){
        Class<Child> cClass = Child.class;
        Class<? super Child> fClass = cClass.getSuperclass();
        // This won't compile
        // Class<Father> father = fClass.newInstance();
        //only produces Object:
        Object obj = fClass.newInstance();
	}
