  • Slowly go trough all Features and convert to optioned
    • Chat
    • Crafting
    • Crate
    • Channel
    • Head
    • Skin
    • Trademark
    • (Keep converting all the other impl)
  • Regarding 1.21
    • Check out what "Tools" are as the naming conflicts with ours (CraftToolComponent)
    • PacketPlayInBlockPlace contains yRot and xRot
    • Heavy changes to PlayerChunk, PlayerChunkMap again,
    • TicketType LIGHT removed
    • BlockAttachedEntity (Leash, ItemFrame, Painting)
    • ARMOR -> HUMANOID_ARMOR
    • Remove Itemstack "trap" code?. Test foxes again for NPE
    • Check how badly findPlayerWithOminousEffect is implemented
    • PathfinderGoalFollowOwner possibly add back that only up to 10 dogs are teleported
    • EnchantmentFrostWalker if(true) return; // kade edit disable frost walker
    • FIx HeightMap.Type.GROWTH_HEIGHTMAP
  • Hotswapping laggyness
    • Increasing these does not help WEBBIGBOISNOW='-XX:+SegmentedCodeCache -XX:NonProfiledCodeHeapSize=32m -XX:ProfiledCodeHeapSize=128m -XX:NonNMethodCodeHeapSize=64m -XX:ReservedCodeCacheSize=224m'
    • A lot of classes are loaded multiple times by multiple classloaders? Is this normal for hotswapping?
    • Bug seems to be from either:
      • Java 21 in general
      • JBR JDK 21
      • Hotswapagent
      • G1GC?
      • (MC changes?)
    • Fixing hotswapping laggyness in Java 21:
      • Simplest fix: Not using G1Gc as it does not seem to be fixable
      • Instead use '-XX:+DoEscapeAnalysis -XX:+UseSerialGC -XX:-SegmentedCodeCache -XX:ReservedCodeCacheSize=96m -XX:StartAggressiveSweepingAt=50'
      • And force a System.GC on every hotswap interaction
      • Force enable UseCodeCacheFlushing, MethodFlushing, NmethodSweepActivity
      • StartAggressiveSweepingAt, SweeperThreshold
