maxHistory 参数的实现方式似乎存在问题。我在时间间隔内滚动多次（这里每分钟），创建以下文件：（maxHistory = 3）
- trace.log（活动文件）
- 跟踪-2013-03-13-16.14.0.log.zip
- 跟踪-2013-03-13-16.13.0.log.zip
- 跟踪-2013-03-13-16.12.2.log.zip
- trace-2013-03-13-16.12.1.log.zip
- trace-2013-03-13-16.12.0.log.zip
下一次翻转发生，16.13.0.log.zip 文件被删除，而不是最旧的文件（12.{0,1,2}，正如我所预料的那样。这是预期的行为吗？
