jvm内置锁synchronized不能被中断

很久没看技术书籍了，今天看了一下《七周七并发模型》前面两章讲的java，写的还是有深度的。看到了一个有demo，说jvm内置锁synchronized是不能被中断的。照着书上写了个demo，验证了一下，是不能被中断

public class Uninterruptible {
    private static final Object o1 = new Object();
    private static final Object o2 = new Object();

    public static void main(String[] args) throws InterruptedException {
        t1.start();
        t2.start();
        Thread.sleep(2000);
        System.out.println("before interrupt");
        t1.interrupt();
        t2.interrupt();
        System.out.println("end interrupt");
        t1.join();
        t2.join();
    }

    static Thread t1 = new Thread(() -> {
       synchronized (o1){
           try {
               System.out.println("start t1");
               Thread.sleep(1000);
               synchronized (o2){
                   System.out.println("t1 lock o2");
               }
           } catch (InterruptedException e) {
               System.out.println("t1 interrupted");
               e.printStackTrace();
           }
       }
    });

    static Thread t2 = new Thread(() -> {
       synchronized (o2){
           try {
               System.out.println("start t2");
               Thread.sleep(1000);
               synchronized (o1){
                   System.out.println("t2 lock o1");

           } catch (InterruptedException e) {
               System.out.println("t2 intterrupted");
               e.printStackTrace();
           }
       }
    });
}
