resolve false negative suppression

[Pankraz76]

add double-check for each suppression to avoid dead-lock suppression stuff thats not existing. like in:

• chore: resolve false negative suppression @SuppressWarnings("checkstyle:UnusedLocalVariable") apache/maven#2369

Just like out whitewords plugin checks for key given but not used. The same principle applies here.

same feature needed in pmd here some context:

• Validate false-negative suppression pmd/pmd#5749
• [core] Add rule to report unnecessary suppression comments/annotations pmd/pmd#5609
• [core] Warn on unneeded suppression pmd/pmd#648

Long awaiting feature, we need design of it

[Pankraz76]

yes, please hit me up. Its possible as we have all information needed.

Having new checker for this, only to check the false negatives.

Some of our suppression are reusable between filters .
Keep in mind that config can be dynamic but suppressions are not, configs can be single file for few projects. We need something that user can activate, run, and cleanup. But all others should not be affected.

no need to waste effort onto checkstyle anymore.

Pretenting to have 100% quality and not passing prone and PMD is a very nice hilarious joke, but not some real considerable software.
