Why is the program terminating?

Question

Scala

object test {
  def main(args: Array[String]) {
    val buf: ArrayBlockingQueue[Integer] = new ArrayBlockingQueue(5)

    for (p <- 1 to 2)
      ExecutionContext.global.execute(() =>
        for (i <- 1 to 10) {println(s"Producer$p producing $i"); buf.put(i)}
      )

    for (c <- 1 to 3)
      ExecutionContext.global.execute(() =>
        for (i <- 1 to 10) {println(s"Consumer$c consumed ${buf.take}")}
      )
    Thread.sleep(1000)
  }
}

Hello, I have a question about the code above. Why is the program terminating?
I thought that the above program should hang because the ArrayBlockingQueue is empty, there are fewer Producers than Consumers and there is nothing more to remove from the Consumer queue.
