Using Java Constructor.newInstance(args) , why the "wrong number of args" error?

Why does this fail with the error :

Args are: -normi -nosplash
Exception in thread "main" java.lang.IllegalArgumentException: wrong 
     number of arguments
    at sun.reflect.NativeConstructorAccessorImpl
    .newInstance0(Native Method)
    at sun.reflect.NativeConstructorAccessorImpl
    .newInstance(NativeConstructorAccessorImpl.java:39)
    at sun.reflect.DelegatingConstructorAccessorImpl
    .newInstance(DelegatingConstructorAccessorImpl.java:27)
    at java.lang.reflect.Constructor.newInstance(Constructor.java:513)
    at TSStack.main(TSStack.java:14)

Here is the code:

public static void main(String args[]) throws Exception {
    System.out.println("Args are: " + args[0]+ " " + args[1] );
        try {
            Constructor<Site> c = Site.class.getDeclaredConstructor();
            c.setAccessible(true); // use reflection to get access to  
                                      //this private constructor
            c.newInstance( (Object[])args );
          } catch (InvocationTargetException x) {
            x.printStackTrace();
          } catch (NoSuchMethodException x) {
            x.printStackTrace();
          } catch (InstantiationException x) {
            x.printStackTrace();
          } catch (IllegalAccessException x) {
            x.printStackTrace();
          }     
}

Site.class.getDeclaredConstructor() will return you default constructor with no arguments, so you must pass it an empty array of arguments which is not the case in your example (otherwise you would fail on the first line with System.out.println()).
