这一行看起来多余，threadPool没有地方使用

这个threadPool变量是ThreadWorkPool的属性，是线程池的实例，会有跟维护ThreadWorkPool生命周期相关的操作

| threadPool = wrappedThreadPool; | ||
| threadPoolMXBean = new ThreadPerTaskExecutorMXBeanImpl(wrappedThreadPool); |

这里代码覆盖需要跑在Java21或者支持fiber的KonaJDK上

useThreadPerTaskThread命名是不是错了，useThreadPerTaskExecutor

threadPool 和threadPoolMXBean 会被覆盖掉

用Executors.newVirtualThreadPerTaskExecutor()的方式使用虚拟线程，用ThreadPerTaskExecutor代替，用完立即销毁
使用ExecutorServiceWrapper去实现ThreadPoolMXBean临时使用反射实现，只简单统计了提交和完成的任务数量，近似替代相关数据监控。JEP#444建议使用JFR来监控虚拟线程。
