Frankly, it looks more like a project configuration issue. Downstream projects that depend on `jmh-core` should not have a dependency on another `jopt-simple`. If they do depend on `jopt-simple` 5.0.4 via the parent POMs or something, then they need to use `<exclusion>` to exclude older `jopt-simple` and let JMH use its own.
