Lot of sonarlint reported issues

[tyge68]

SonarLint report a lot of issues that would make sense to fix to improve code quality

To reproduce , open the project code using Eclipse IDE + SonarLint extension and analyze the repository.

Thanks @tyge68 for bringing this up! I know there are lint issues in the code, but I would first start by determining the list of rules that we want to enforce, otherwise different IDEs will complain about different things and devs will keep changing back and forth.

I see sonarlint is available for idea also, but do you know if it's possible to add it to the maven build so we can have an automated check?
