Use JMS 2.0 functionality

Use JMS 2.0 functionality

JMS 2.0 introduces several new areas of functionality to the IBM MQ classes for JMS.

When you are developing a JMS application for IBM MQ Version 8.0 or later, you might need to consider the impact of this functionality on your queue manager.

JMS 2.0 delivery delay
With JMS 2.0, we can specify a delivery delay when sending a message. The queue manager does not deliver the message until after the specified delivery delay has elapsed.
Cloned and shared subscriptions
In IBM MQ Version 8.0 or later, there are two methods for giving multiple consumers access to the same subscription. These two methods are by using cloned subscriptions, or by using shared subscriptions.
SupportMQExtensions property
The JMS 2.0 specification introduces changes to the way certain behaviors work. IBM MQ Version 8.0 and later includes the property com.ibm.mq.jms.SupportMQExtensions, which can be set to TRUE, to revert these changed behaviors back to previous implementations.
