                Node n1 = new Node(i);
                Node n2 = new Node(i+1);
                TestUnsafe t = new TestUnsafe(n1);
                Node old = t.foo(n2);

                if(old.next.v > 20000) {
                   System.out.println("not enter here" + old.next.v);
                }
            }
          }
          TestUnsafe(Node n) {super(n);}

          public Node foo(Node n) {
            Node old;
            old = this.getAndSet(n); // inline sun.misc.Unsafe::getAndSetObject here
            old.next = n;
            return old;
          }
        }
