The document discusses plans for Jakarta Messaging 3.x, which will serve as the basis for the JMS API in Jakarta EE 9 and beyond. It outlines the timeline of JMS specifications and their inclusion in Java EE and Jakarta EE. Ideas for Jakarta Messaging 3.x include incorporating unreleased features from JMS 2.1, improving support for CDI, adding property conversion and JSON-B message support, and developing a MessagingClient similar to MicroProfile Rest Client. The presentation encourages involvement in the Jakarta Messaging and sample code projects on GitHub.

LEARNING FROM JAX-RS
● No interfaces
● Fluid method signatures
● Annotation-based configuration
● Strongly Typed
● Self-documenting
● Targeted: annotations can be on
○ Class, Method, Parameter, Field
