Monkey Patches

Added

• Physics Mod vine unload fix
  • DoublyLinkedListMixin: Skips removeNode for nodes that aren't linked into the list, and detaches all nodes in clear()
  • Resolves NullPointerException: Cannot assign field "next" because "node.prev" is null in net.diebuddies.util.DoublyLinkedList.removeNode when Sodium deletes chunk sections with vine physics (e.g. at the end of a resource pack reload), and the follow-up IllegalStateException: Worker threads are not running crash
  • Not reported upstream (Physics Mod Pro is closed source)
  • Only loads for Physics Mod 3.0.32 (Pro v185)
  • Configuration option: patches.physicsmod.vine_unload_fix_enabled (default: true)

Technical Details

• PhysicsWorld.destroy() calls DoublyLinkedList.clear(), which drops head/tail but leaves nodes linked and stored on their elements; removing the old first element later takes the middle-node branch with a null prev
• Physics Mod isn't available at compile time: the Node parameter is taken as @Coerce Object, and LinkedListGuard reaches private fields through a MethodHandles.Lookup created inside the target class
