Hi @ipolevoy, since this is about upgrading dependencies, can I make some questions?

1. Have you considered asking the people from Moderne to include JavaLite in the Moderne App to facilitate such updates and code refactorings? https://app.moderne.io/
2. About the PostgreSQL dependencies, do you have a roadmap or time horizon to validate the 42.6.0 (and usage of Virtual Threads)?
3. Is there a roadmap or time horizon to upgrade to Java 17 and then to Java 21? For the easier aspects, I think that OpenRewrite/Moderne could be useful, but then would have much more for all the troubleshooting and edge cases of functional requirements...

Since I have noticed that basically is you who does most (all) of the maintaining, I am also curious how many people are currently involved in this project.

@lobaorn we will take a look at that, thanks

@yanchevsky I committed a first take, changes in poms. It is yours now.

@yanchevsky I'd like to release the one and only version for Java 16. I think this task is already stale. Can you please take a quick look?

this is done
