/** A client uses a {@code QueueReceiver} object to receive messages that 
  * have been delivered to a queue.
  *
  * <P>Although it is possible to have multiple {@code QueueReceiver}s 
  * for the same queue, the JMS API does not define how messages are 
  * distributed between the {@code QueueReceiver}s.
  *
  * <P>If a {@code QueueReceiver} specifies a message selector, the 
  * messages that are not selected remain on the queue. By definition, a message
  * selector allows a {@code QueueReceiver} to skip messages. This 
  * means that when the skipped messages are eventually read, the total ordering
  * of the reads does not retain the partial order defined by each message 
  * producer. Only {@code QueueReceiver}s without a message selector
  * will read messages in message producer order.
  *
  * <P>Creating a {@code MessageConsumer} provides the same features as
  * creating a {@code QueueReceiver}. A {@code MessageConsumer} object is 
  * recommended for creating new code. The  {@code QueueReceiver} is
  * provided to support existing code.
