Jörg,
I don't want to discourage you but I don't see a lot of your libraries using Jakarta EE yet, so maybe this could be the wrong list to advertise it?🤔
Making heavy use of the "Jigsaw" JPMS is a good thing at least in my opinion but I got quite confused between "base", "main" and "core" among all your modules sometimes. It also seems quite odd, that it is still at 0.2.x after more than 20 years (the copyright header says 2001-2021)
Many of those ideas probably come late, the biggest overlap seems with JSR 377, which not very surprising is now dormant:
https://jcp.org/en/jsr/detail?id=377, I can't say if you are a Full JCP Member already nor if 377 could ever leave the dormant state, but most of the modules I see in your library are much more desktop or "RCP" focussed and only very few of them have anything to do with Jakarta EE. The "config" module but there are already many "cooks" involved in that kitchen, so it could be a little late there, but stay tuned and maybe subscribe to some of the detail "dev" spec lists for JSON, Validation or (if it came into existence) Jakarta Configuration.
For all the other stuff like JavaFX or JEPs, you're just in the wrong place here.
