Examples of com.hazelcast.core.ICondition

com.hazelcast.core.ICondition
Distributed implementation of {@link Condition}. An ICondition instance is created using {@link ILock#newCondition(String)}
```
 HazelcastInstance instance = ...; ILock lock = instance.getLock("lock"); ICondition cond = lock.newCondition("condition"); ... 
```
@see Condition @see ILock

    @Test(timeout = 60000)
    public void testAwaitUntil_whenSuccess() throws InterruptedException {
        HazelcastInstance instance = createHazelcastInstance();


        final ILock lock = instance.getLock(randomString());
        final ICondition condition = lock.newCondition(randomString());
        final CountDownLatch latch = new CountDownLatch(1);


        new Thread(new Runnable() {
            @Override
            public void run() {
                lock.lock();
                try {
                    Date date = new Date();
                    date.setTime(System.currentTimeMillis() + 10000);
                    if (condition.awaitUntil(date)) {
                        latch.countDown();
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
