为什么隐式锁没有发生死锁？(Why deadlock is not happening for implicit locks?)

 什么是可重入锁定和概念？ 说 
 
 
 
 如果一个锁是不可重入的，你可以抓住锁，然后当你再次抓住它时阻塞，有效地使你自己的进程陷入僵局。 
 
 
public class ImplicitLock {

synchronized public void test1() {
    System.out.println("enter test1");
    test2();
    System.out.println("exit test1");

}

synchronized public void test2() {
    System.out.println("inside test2");

}

}
 
 从主班，我执行 
 
ImplicitLock lock1 = new ImplicitLock();
lock1.test1();
 
 我得到了以下输出虽然我期待死锁，当按照SO隐式锁定描述调用test2但它没有 
 
enter test1
inside test2
exit test1

What is the Re-entrant lock and concept in general? says
 
 
 
If a lock is non re-entrant you could grab the lock, then block when you go to grab it again, effectively deadlocking your own process.
 
 
public class ImplicitLock {

synchronized public void test1() {
    System.out.println("enter test1");
    test2();
    System.out.println("exit test1");

}

synchronized public void test2() {
    System.out.println("inside test2");

}

}
 
From main class , i executed
 
ImplicitLock lock1 = new ImplicitLock();
lock1.test1();
 
I got the below output though i was expecting deadlock when call goes for test2 as per SO implicit lock description but it didn't
 
enter test1
inside test2
exit test1
