      1. Define a public service similar to the movie.
      2. Add a rate limit policy say 10 request per minute.
      3. Go into Rest client, invoke the services n times (not quite sure what n was, seems to be less than 10), but I did get a 429 which I thought was good.
      4. I then waited for a little while.
      5. I tried the Rest client again, I invoked the services over 10 times, many times but I never saw the 429 again.
      6. This was odd. So I stopped the server.
      7. Restart the server.
      8. Try to invoke the same service again, and I got the NPE.

      Pls let me know if you can reproduce. Thx.
