/**
 * Use {@link RabbitAdmin#initialize()} to redeclare everything if necessary.
 * Since auto deletion of a queue can cause upstream elements
 * (bindings, exchanges) to be deleted too, everything needs to be redeclared if
 * a queue is missing./*from   w  w  w .  ja  va 2  s. c  o m*/
 * Declaration is idempotent so, aside from some network chatter, there is no issue,
 * and we only will do it if we detect our queue is gone.
 * <p>
 * In general it makes sense only for the 'auto-delete' or 'expired' queues,
 * but with the server TTL policy we don't have ability to determine 'expiration'
 * option for the queue.
 * <p>
 * Starting with version 1.6, if
 * {@link #setMismatchedQueuesFatal(boolean) mismatchedQueuesFatal} is true,
 * the declarations are always attempted during restart so the listener will
 * fail with a fatal error if mismatches occur.
