* Variant of the standard JMS {@link jakarta.jms.MessageListener} interface,

* JMS Session object. The latter can be used to send reply messages,
* without the need to access an external Connection/Session,
* i.e. without the need to access the underlying ConnectionFactory.
*
* <p>Supported by Spring's {@link DefaultMessageListenerContainer}
* and {@link SimpleMessageListenerContainer},
* as direct alternative to the standard JMS MessageListener interface.
* Typically <i>not</i> supported by JCA-based listener containers:
* For maximum compatibility, implement a standard JMS MessageListener instead.
