Fix PMD 7.1.0 Violations

[mahfouz72]

After migrating To PMD 7.1.0, it caught new violations in our Codebase (#14856 (comment)). We should investigate this list and fix all violations if they are valid. if a violation is a false positive it should be reported to PMD

the suppressions were added in 5a1f41e
List of violations: https://gist.github.com/mahfouz72/d199fca33ce2c9e8d84be3882403093c

we should split down the list to make the fix easier so a few PRs are fine

Please inline violations in text format, not xml. It much easier to read for humans.
