How to use reflection to invoke a method which takes a varg as an argument?

I am trying to use reflection to invoke a method which takes a varg as an argument.

This is the method I am trying to invoke

public void serve(Object... args) 
{
    System.out.println("Hi!");
}

This is my code to invoke this method through reflection

Object[] params = new Object[] {new Object(), new Object()};

Class<?> cls = Class.forName("com.reflec.Serve");
Service service = (Service) cls.newInstance();
for(Method method : cls.getMethods())
{
    if(method.getName().equals("serve"))
    {
        method.invoke(service, params);
    }
}

However I keep getting the following error java.lang.IllegalArgumentException: wrong number of arguments

Anyone got any ideas?
