        public void removeUserFromCache​(java.lang.String username)
        Description copied from interface: UserCache
        Removes the specified user from the cache. The username is the key used to remove the user. If the user is not found, the method should simply return (not thrown an exception).

        Some cache implementations may not support eviction from the cache, in which case they should provide appropriate behaviour to alter the user in either its documentation, via an exception, or through a log message.
