> expect to work like tomcat thread pool
> but jdk standard thread pool's behavior is different:
> JDK standard thread pool rules:
> * 1.use core threads.
> * 2.if all core threads are busy, then queue the request.
> * 3.if queue is full, then create new thread util reach the limit of max
> threads.
> * 4.if queue is full, and threads count is max, then reject the request.
>
> to do what we want, need to lock the executor several times for one task,
> that's too bad
> so only make compatible to old version temporary
