Cannot Make Static Reference To Non-static Type String

I am writing the following program in Java SE 7. It throwing "Cannot make a static reference to the non-static type String" . However if I write parameterised String inside main method as  java.lang.String[] args, it compiles fine.
 
class MainClass<String> {
  <T> MainClass(T t) {
   System.out.println(t.getClass().getName());
  } 
  public static void main(String[] args) {
  System.out.println("asdasd");
   new MainClass<>("");
  }
}
 
I mean following programs compile fine in Java SE 7 :
 
class MainClass<String> {
  <T> MainClass(T t) {
   System.out.println(t.getClass().getName());
  }
  public static void main(java.lang.String[] args) {
  System.out.println("asdasd");
   new MainClass<>("");
  }
}
