技巧是将断点挂起策略设置为- Thread。查看断点属性（右键单击断点）

一旦完成，线程将遇到断点和阻塞，现在可以切换活动线程以检查竞争条件/死锁。

下面是创建死锁的代码段：

public static void main(String args[]) {
    Thread thread1 = new Thread(null, new MyThread(obj1, obj2), "Thread-1");
    Thread thread2 = new Thread(null, new MyThread(obj2, obj1), "Thread-2");
    thread1.start();
    thread2.start();
}
class MyThread implements Runnable {
    private Object obj1;
    private Object obj2;

    MyThread(Object obj1, Object obj2) {
        this.obj1 = obj1;
        this.obj2 = obj2;
    }

    @Override
    public void run() {
        System.out.println("Acquiring locks");
        synchronized (obj1){
            System.out.println("Acquired 1st lock");
            synchronized (obj2){
                System.out.println("Acquired 2nd lock");
            }
            System.out.println("Released 2nd lock");
        }
        System.out.println("Released 1st lock");
    }
}

您可能会对调用堆栈的另一种线程视图感兴趣，通过单击“恢复线程视图”按钮启用：

关于这一点的文档：Debug Tool Window - Threads
此外，这些问题可能有用：

1. IntelliJ Thread Debug
2. IntelliJ - pause a thread while debugging
