It's about time to simplify things (in the java universe & enterprise) and this is a good first effort, all the best!
This goes way beyond that; a whole set of dependencies that are very thoughtfully designed. If they maintain backwards compatibility, as the JDK stdlib does, for essentially ever, I might bite. I've seen a lot of these type of things come and go.
Some of the projects are actually forks from some of my open source from the company I founded (and later sold). Some have been around for quite a while (10+ years) and have some adoption as well.
To keep those projects going, I forked them and started Latte.
My plan is to keep working on all the projects and really start promoting it. I think it's a game changer for Java.
I'm currently working on adding HTTP/2 to our HTTP server. It's nearly done and looking really solid. And our benchmarks on it are looking like we'll be the second fastest HTTP server for Java.
