For backend frameworks, I'd look at Quarkus [1] or Micronaut [2]. Both are geared towards configuration, async processing and native compilation, along with a ton of options to integrate with external systems.

For something a bit lighter weight, Vert.x [3] is a good option (Quarkus is based on it).

[2] - https://micronaut.io/

You'll need Java 1.8+, and Maven or Gradle for the toolchain (I prefer the former). Intellij is the best IDE but I get by with VSCode.

There's no reason to use 10 years old version of Java. Use 17.

True. I was just stating the minimum level.
