Maybe you are? Yes, it integrates existing frameworks and libraries. In fact, the home page says "Dropwizard is a Java framework for developing ops-friendly, high-performance, RESTful web services."

While I would love to argue whether DropWizard is a framework or not there is no need for that.

Just go to google trends and compare Spring and Dropwizard. Or look at https://www.jetbrains.com/lp/devecosystem-2021/java/. Dropwizard doesn't even appear in the list of web frameworks.

I mean, if you still believe that Java has as many frameworks as Javascript has (and had in the past) there is nothing I can say that will convince you.

I've been using Java on and off since 1996. It absolutely has had a ton of frameworks over the years. Yes, I realize many of them are niche or no longer in use, but that doesn't mean there isn't a legacy application where you have to maintain 10 or 20 year old garbage.

FYI, I despise both J2EE and Spring. (Maybe Spring Boot is okay.)

Spring Boot is recapitulating the worst parts of old (like, 3.0-era) Spring. It's the biggest step backwards in programming history since... I actually can't think of anything worse.
