    Executing this multiple times occasionally shows 2 non daemon threads that are not letting application die. Those threads go away generally with in a minute. Those 2 threads are shown below. Is there a reason for them to be non daemon? public static void main(String[] args) throws IOException { CassandraCluster cluster = CassandraCluster.builder(). withContactPointsLocator(localContactPointsLocator). withClusterName(clusterName). withDataCenter(datacenter). withApplication(clusterName). build(); Session session = cluster.connect(); session.close(); cluster.close(); System.out.println("Main thread finished!"); } "Cassandra Java Driver blocking tasks worker-1" prio=5 tid=7fb6a10b9800 nid=0x115e8f000 waiting on condition [115e8e000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for <7f4532b90> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject) at java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:196) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos(AbstractQueuedSynchronizer.java:2025) at java.util.concurrent.LinkedBlockingQueue.poll(LinkedBlockingQueue.java:424) at java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:955) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:917) at java.lang.Thread.run(Thread.java:695) Locked ownable synchronizers: - None "Cassandra Java Driver blocking tasks worker-0" prio=5 tid=7fb6a10b9000 nid=0x115d8c000 waiting on condition [115d8b000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for <7f4532b90> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject) at java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:196) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos(AbstractQueuedSynchronizer.java:2025) at java.util.concurrent.LinkedBlockingQueue.poll(LinkedBlockingQueue.java:424) at java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:955) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:917) at java.lang.Thread.run(Thread.java:695) Locked ownable synchronizers: - None
