InitExecutor-->doInit(),初始化的小问题

public static void doInit() {
if (!initialized.compareAndSet(false, true)) {
return;
}
......
}
这个方法的开头是否考虑加上下面这行代码
if(initialized.get()) return;
防止已经进行了初始化,还要执行一次代价相对高一点的CAS操作

Start by locating InitExecutor.doInit() and read the existing initialized flag and compareAndSet flow. Check how initialization is called and whether concurrent callers can safely return early; done means the proposed fast path is validated without changing one-time initialization behavior, with relevant tests or measurements updated if they exist.
