I guess if we want to make progress on this, we will probably have to evaluate every individual warning separately, and add those which does make sense (e.g. `import-preprocessor-directive-pedantic`), and ignore the rest. I personally will not have time nor interest in driving this forward, at least not right now. ------------- PR Comment: https://git.openjdk.org/jdk/pull/17687#issuecomment-2056659089
