问为什么在静态方法和类中同步得到不同的java字节码

EN

package com.hao.thread;

public class Main {
    private static int count = 10;

    public synchronized static void m1() {
        --count;
        System.out.println(Thread.currentThread().getName() + " count = " + count);
    }

    public static void m2() {
        synchronized (Main.class) {
            --count;
            System.out.println(Thread.currentThread().getName() + " count = " + count);
        }
    }

    public static void main(String[] args) {

    }
}
