retained heap是2M吗？ 这样的话，占比也不多吧

并且FileOutputStream 占比是 0.01%吧？
看上去代码 finally中，是有close的吧？

可以看到这边应该是已经close掉了

但是目前看，这种写一次logger，就进行一次fos的创建，会导致后期的GC难度变大。
看了笨神的文章：http://lovestblog.cn/blog/2015/07/09/final-reference/
这边介绍是fos会在内存中不断堆积，从而产生后续的gc问题。
从dump中看，一次占用0.01%的量还是很恐怖的

用github比较少，可以在搜索微信：deniulor，方便沟通，dump文件可以直接发送给你

下面的这一个版本日志控制器会换成LOGBACK。。不会使用这个老的日志控制器处理了。所以
