Hi Jorge, Great to hear that someone is taking a dive and switching to Java modules!
I am pretty sure that making "cayenne-server" compatible with JPMS should be fairly straightforward. We support OSGi, that IIRC has even tighter constraints around modules. So all the packages are already organized properly, etc. Just need to figure out proper metadata when assembling the jars. Less sure about ROP (as you see, it is giving you much more trouble). But nothing prevents us from doing a package reorg there as well. So while I am not aware that anyone has looked at JPMS-compliant packaging for Cayenne, I think we should, and this totally doable. So I'd say this is just a question of time. BTW if you want to take a shot at it yourself, this would be great too. Myself (and I am pretty sure others here) will be happy to answer any questions and review your PRs :) Andrus P.S.
