Remarks
Listen is useful in situations that require waiting until a message is available in the queue for consumers whose names are specified in listenConsumers.
This call blocks the calling thread until there is a message ready for consumption for a consumer in the listenConsumers array. It returns a string representing the consumer name for which the message is ready.The method returns null if a timeout occurs.
The listenConsumers parameter should be null for single consumer queues. An empty string is returned in such cases.
A waitTime of -1 implies infinite wait time.
