What message distribution policy does the JMS API specify when there are two or more QueueReceivers for the same queue at the same time?

The JMS API does not specify a message distribution policy when two or more QueueReceivers are registered with a destination at the same time. JMS API semantics account for only one QueueReceiver at any point in time. The JMS API does not prohibit multiple QueueReceivers for a queue; it just does not define the behavior for this case.
