**现象：** _Simple Consumer 消费FIFO队列时，未对前一条消息执行确认（ack）的情形下，可以接收并确认下一条消息。_ 这似乎违反了FIFO语义，请问是否为Bug。 操作步骤： 1. Simple Consumer 工作线程循环调用 `receive()` 方法接收FIFO队列消息 2. Producer 向 Simple Consumer 发送 FIFO 消息 A 3. Simple Consumer 接收到消息 A 后不确认（不调用 `ack()`） 4. Producer 向 Simple Consumer 发送 FIFO 消息 B 5. Simple Consumer 会收到 FIFO 消息 B 6. Simple Consumer 确认消息B（`ack(B)`）成功 7. 过一段时间后，Simple Consumer 会收到消息 A 的重试消息 -- This is an automated message from the Apache Git Service.
