Various cleanups in instrumentation-jvm

Same as #1012, let's see if the build runs here

[mimaison]

Here the build fails because of spotless issues in the prometheus-metrics-model module which this PR does not touch: https://github.com/mimaison/client_java/actions/runs/11127458358/job/30919802107

I wonder if we should apply spotless across the whole project at once, and then restart working on code changes.

problem seems to be that the action runs in your repo - where origin/main is different - that's why the build check here is not working

wondering that too - makes it easier to review changes

Awesome, let me rebase!
