Right, okay, so the last option wins, this is good. We can do what the updated version does. ...but then we also need to handle platforms where `-XX:-CompactStrings` is set by platform config (e.g. on ARM). `-XX:+CompactStrings` would be ignored there, and we cannot run test with `true` then. I think only ARM32 is affected, so it would be filtered by existing `@requires`, so it can be resolved later.
