I've written ORMs for both Java and Go and agree that Java is a wonderful language with a much more complete type system than Go. However, it feels like Java web development teams typically suffer from not having their own Wagtail/Payload/etc and build way too much from scratch. Maybe there is some great open source framework+CMS out there making waves in Java land that I'm unaware of?
Framework _and_ CMS so most of these don't seem to apply. I haven't seen Vaadin before so that's interesting. JHipster seems like the closest to the ones I mentioned but the UI looks unpolished in the overview video.
