AntiAFKPlus v2.4.2 Changelog

🎯 Complete Folia 1.21.8 Compatibility

Problem Resolved

Issue: The plugin failed to initialize on Folia 1.21.8 with UnsupportedOperationException (due to BukkitScheduler usage) and reflection errors in runAtFixedRate.

Root Cause: PlatformScheduler was using incorrect method signatures for Folia's GlobalRegionScheduler API, causing reflection failures during task scheduling.

Error Stack:

Failed to schedule Folia repeating task: io.papermc.paper.threadedregions.scheduler.FoliaGlobalRegionScheduler.runAtFixedRate
Module system initialization failed: Cannot schedule repeating task on Folia without working scheduler

Technical Solution Implemented

🔧 Correct Folia Method Signatures

• Before: runAtFixedRate(plugin.getClass(), Consumer.class, long.class, long.class, TimeUnit.class)
• After: runAtFixedRate(Plugin.class, Consumer.class, long.class, long.class)
• Key: no TimeUnit parameter and timing in ticks directly (no ms conversion)

🛡️ Stronger Fallback

• Always create a ScheduledExecutorService fallback before reflection
• Graceful degradation if native Folia API fails
• Dedicated daemon thread pool for fallback operations

⚡ Additional API Fixes

• Adjusted runDelayed and run signatures for single-execution tasks
• Corrected RegionScheduler and EntityScheduler parameter types
• Consistent use of Consumer<ScheduledTask>

What’s Fixed

• ✅ Full Folia 1.21.8 compatibility: initializes and runs correctly
• ✅ No UnsupportedOperationException: removed BukkitScheduler usage in Folia context
• ✅ Timers and tasks migrated to PlatformScheduler: pattern analysis, detectors and checks operational
• ✅ Commands and AFK detection working
• ✅ Zero impact on other servers: Paper, Spigot, Bukkit, Purpur unchanged

Compatibility

• Paper/Spigot/Bukkit: ✅ unchanged, functionality preserved
• Purpur: ✅ compatible via Paper base
• Folia 1.21.8+: ✅ complete native support with correct API usage
