AnarchySpawn

[1.1.0] - 2026-10-15

Added

• Full Compatibility for Minecraft 26.3+ (1.21.x):
  • Extended PaperCompatibility reflection layer to dynamically resolve 26.3 / 1.21.x Bukkit & Paper API features, sound effects (BLOCK_TRIAL_SPAWNER_SPAWN_MOB, ITEM_WIND_CHARGE_WIND_BURST, BLOCK_CREAKING_HEART_SPAWN), and particle effects (PALE_OAK_LEAVES, CREAKING_CRUMB, TRIAL_SPAWNER_DETECTION, WIND_CHARGE).
  • Added full safety inspection rules in SafetyValidator for 26.3 blocks (CREAKING_HEART, EYE_BLOSSOM, PALE_HANGING_MOSS, HEAVY_CORE, RESIN_BLOCK, RESIN_CLUMP) and biome support (PALE_GARDEN) with automatic fallback to safe alternatives on older servers (1.12.2 - 1.20.x).
  • Updated metadata, documentation, and version matrix to reflect full 1.12.2 - 26.3+ runtime support across Paper, Purpur, Folia, and Spigot.
• Full Backward Compatibility Down to Minecraft 1.12.2:
  • Implemented dual-track persistence in PDCUtils: dynamically leverages native PersistentDataContainer (PDC) on 1.14+ while seamlessly degrading to thread-safe local file storage (data/players.yml) on 1.12.2 - 1.13.2.
  • Added legacy material support (STATIONARY_LAVA, STATIONARY_WATER, BURNING_FURNACE, BED_BLOCK, etc.) and insulated 1.13+ class references (BlockData, Waterlogged, Tag) to prevent NoClassDefFoundError on legacy runtimes.
  • Guarded against Material.isBlock() and Material.isAir() API absence on pre-1.13/pre-1.14 servers.
• Surface Direct Penetration & HighestBlockY Optimization:
  • Integrated world.getHighestBlockYAt(x, z) direct heightmap penetration in SafeLocationFinder for Overworld dimensions, reducing column block inspections from ~250 down to 1~3 iterations (a 98%+ speedup in safe spawn searches).
  • Implemented narrow search window (surface +6 down to -12) around surface terrain for immediate candidate evaluation, with graceful fallback scanning for caves and Nether bedrock ceilings.
• Introduced DeathHotspotManager and PlayerDeathListener for dynamic death/combat hotspot tracking and avoidance.
• Added death-hotspots configuration block in config.yml with customizable toggles (enabled), avoidance radius (radius), expiration duration (ttl-seconds), and max hotspots stored per world (max-hotspots-per-world).
• Implemented two-phase search in SafeLocationFinder: primary phase filters candidate spawn points using death hotspot blacklists, while secondary fallback phase automatically ignores hotspot restrictions if primary search fails to find a valid location, ensuring players always spawn normally in the wilderness.
• Added PlayerQuitListener and TeleportService.cancelPlayerProtection() to reset invulnerability and cancel protection tasks on player disconnect, eliminating combat-logging permanent god-mode exploits.

Fixed

• Folia Chunk Region Confinement Overload (Critical): Added runForRegion(plugin, world, chunkX, chunkZ, task) overload in FoliaScheduler. Fixed SafeLocationFinder and PaperCompatibility.getChunkAtAsync dispatching to default chunk (0, 0) instead of the target chunk coordinates (targetX >> 4, targetZ >> 4), which would trigger Folia cross-region thread confinement violations when reading/loading blocks outside chunk (0,0).
• Fallback Respawn Interim Damage Protection: Granted 60-tick damage immunity (noDamageTicks) in PlayerRespawnListener when falling back to the world spawn while background async search resolves, preventing instant deaths at hostile fallback points.
• PlaceholderAPI Hotspots Placeholder & Null Guards: Added %anarchyspawn_hotspots_<world>% placeholder for active hotspot monitoring, and added null-safety checks in PlaceholderAPIHook to guard against disabled cache/hotspot services.
• PlayerDeathListener Lifecycle Guard: Added defensive null checks for entity and DeathHotspotManager in PlayerDeathListener to ensure zero errors during reload or shutdown.
• Cache In-Flight Permit Leak Guard: Wrapped column evaluation inside FoliaScheduler.runForRegion in try-catch(Throwable), guaranteeing async CompletableFutures always resolve and never freeze cache pool refills.
• Folia scheduler reflection signature fix (critical): Corrected erroneous probe of non-existent Bukkit.getRegionizedScheduler() and scheduler.player(); now correctly resolves Bukkit.getRegionScheduler(), Bukkit.getGlobalRegionScheduler(), Bukkit.getAsyncScheduler(), and dynamically retrieves player.getScheduler() (EntityScheduler) per entity on Folia.
• Cache Pool Hotspot Bypass: Fixed LocationCachePool.poll() failing to check whether pre-cached coordinates became active death hotspots after being cached.
• Respawn Effects Timing: Switched PlayerRespawnListener to schedule post-respawn effects with a 1-tick delay (runForPlayerLater(..., 1L)), preventing potion effects, sounds, titles, and invulnerability from being skipped while the entity is still completing respawn.
• Empty Biome Blacklist Guard: Guarded against blank or empty strings in safety-filter.biome-blacklist matching all biomes via contains("").
• Annular Radius Math Safety: Enforced Math.min/Math.max bounds in SafeLocationFinder to prevent Math.sqrt of negative numbers (NaN) when radius configs are inverted.
• Hotspot Cache Reset on Reload: Added deathHotspotManager.clearAllHotspots() to /as reload.
• Dynamic Author in PlaceholderAPI: Dynamically resolved plugin author from plugin.yml in PlaceholderAPIHook.
• Fire Coral & Mud Brick False Positives: Fixed DANGEROUS_SURROUNDING_MATERIALS accidentally classifying safe FIRE_CORAL blocks as lethal fire, and refined MUD floor checking so that building blocks like MUD_BRICKS and PACKED_MUD are not falsely treated as unstable.
• Cross-World Join Race Condition: Added world-consistency validation in PlayerJoinListener after the initial join delay to prevent cross-world conflicts with lobby/auth plugins.
• TeleportService Protection Task Field & Session Safety: Resolved missing activeProtectionTasks compilation variable; introduced session-token tracking (activeProtectionSessions) ensuring safe protection cancellation and preventing stale callbacks on Folia.
• Folia Cross-Region Command Messaging: Fixed /as tp and /as test violating Folia thread confinement by dispatching command feedback to the sender's own region thread instead of the target's thread.
• Folia Repeating Task Cancellation & Lifecycle Guard: Added runTimerGlobalTask and reflective cancelTask to FoliaScheduler along with isRunning lifecycle checks in LocationCachePool, preventing recurring refill tasks from leaking on Folia during /as reload.
• Hotspot Fallback Attempt Optimization: Short-circuited the secondary 35-attempt fallback pass if getActiveHotspotsCount(world) == 0, preventing redundant chunk operations when search failures are unrelated to hotspots.
• Clean Shutdown Memory Pruning: Added deathHotspotManager.clearAllHotspots() to onDisable() to prevent lingering world references.
• Tab Completer World Name Casing: Preserved configured world name casing in /as tab completions.
