Build & Test (NowChessSystems) TeamCity build finished
A stored java.util.Random field is reachable from BotController's static openingBook, so GraalVM baked it into the image heap and aborted the native build (Random in image heap has a cached seed). Use ThreadLocalRandom.current() at call time instead — no stored instance, nothing in the image heap, still thread-safe. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
