Yes, it really is. SpringBoot especially has so much unnecessary complexity built in. I'd dread having to debug any non-trivial application written using any of the most popular Java frameworks.
Spring Boot basically attempts to turn Java from its statically compiled origins to an annotation-ladled mess full of runtime reflections and compiler pluginitis.
If you're doing that, why not just go the whole hog and use an actually dynamic language and a framework that plays up the language's strengths instead of working _around_ it?
SpringBoot epitomizes the worst of the marriage between an OO fetishist and an enterprise "architect."
