TheFastLaunch v-b1.9.1 Release Notes

This hotfix release consolidates critical compatibility fixes and multithreaded loading enhancements:

🛡️ 1. Forgery / Fabrication Compatibility (Fixes #4)

  • Added dynamic detection for the Forgery / Fabrication mod.
  • Safely bypasses early entity background preloading and potentially conflicting mixins when Forgery is active, completely eliminating MixinEntity injection crashes.

🐛 2. ModernFix Compatibility & Async Error Logging (Fixes #5)

  • Resolved ClassCastException: Protected ModernFix's DynamicBakedModelProvider from being improperly wrapped by Collections.synchronizedMap in ModelBakery.
  • Eliminated Silent Failures: Attached an asynchronous whenComplete error logging listener to ModelManager.reload to properly output exception stack traces instead of locking up the resource reload barrier.
  • Worker Pool Optimization: Restored clean background thread execution for resource reloading while preserving multi-core parallel baking on FastLaunch Quiet Worker Pool.

⚡ 3. Robust Multi-Core MBD2 Parallel NBT Loader

  • High-Performance Multithreaded Loading: Parallelizes NBT parsing across ForkJoinPool for heavy multiblock definitions (including massive 160MB+ files such as sfr.mb).
  • Hybrid NBT Binary Decoder: Uses NbtIo.read (uncompressed NBT) natively with automatic graceful fallback to NbtIo.readCompressed, ensuring 100% data integrity with zero parse dropouts.
  • Full Recursive Directory Walk: Fully traverses subdirectories using Files.walkFileTree identical to MBD2's native structure.
  • Deterministic Thread-Safe Registration: Decodes heavy NBT bytes in parallel across all CPU cores, then sequentially dispatches definitions on the caller thread to eliminate race conditions on non-thread-safe consumers (HashSet, EventBus, GUI configurators).
  • Safe Fallback: Any unexpected scanning error automatically falls back to MBD2's native loader without canceling execution.
