What Spring Developers Should Know About Jakarta EE

Spring Framework and Spring Boot build on a surprisingly large set of Jakarta EE APIs and implementations. This means that it is a great advantage for a Spring developer to be aware of what is going on with the development of Jakarta EE.

Come to this session to learn about the planned changes to the technologies that Spring depends on. There will be demos, and even some AI involved.
