    The default Spring configuration for a JMS Listener sets the receive timeout (a polling loop timer) too low for a cost-effective solution with IBM MQ. See this article for more information. This class will override that default value if it is not explicitly set in the application properties. The application still has control though. If the app sets the value via a call to the listener.setReceiveTimeout method, then that still will be honoured as it comes after the creation and initial attribute setting of the listener object. This method is invoked early in the cycle, once the application environment has been loaded. We then get the opportunity to inspect and add to the environment that will be used later on by the JMS Listener initialisers. This allows the MQ JMS listener to have a different effective default than other JMS providers. Support for this property within Spring Boot itself was added in version 2.2.0
