    static boolean t2runned = false;

public static void main(String[] args) throws Exception {

Thread t1 = new Thread(() -> {
            synchronized (lock) {
                while (!t2runned) {
                    try {
                        lock.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                log.debug("1");
            }
        }, "t1");

Thread t2 = new Thread(() -> {

                log.debug("2");
                t2runned = true;
                lock.notify();
