  27  * @run main/othervm NoneReplayCacheTest
  28  * @summary the replaycache type none cannot stop an authenticator replay,
  29  * but it can stop a message replay when s.s.k.acceptor.subkey is true.
  30  * You should not really use none in production environment. This test merely
  31  * shows there can be other protections when replay cache is not working fine.
