According to https://issues.apache.org/jira/browse/LEGAL-450, it's OK to use a GPL linter. And a project can use GPL "build tools provided they leave no code traces (licensed under a cat X license) in your final release artifacts".
In Calcite we use jmh on the understanding that it does not produce any artifacts and therefore was acceptable. Can someone explain how a benchmarking utility is different from a linter?
