Hey there.
Please take a look at this post on reporting false-positives.
You’ll need to provide a text-based snippet of code, and make sure the issue can be reproduced on the latest version of SonarQube’s Community Build.
Only the latest version of SonarQube Community Build is considered active, so you’ll need to upgrade and see if the false-negative can still be produced!
Your upgrade path is:
9.9.0 → 24.12 → 25.5
