 * @run main/othervm NoneReplayCacheTest

 * @summary the replaycache type none cannot stop an authenticator replay,

 * but it can stop a message replay when s.s.k.acceptor.subkey is true.

 * You should not really use none in production environment. This test merely

 * shows there can be other protections when replay cache is not working fine.
