- In 1.17, EntityTrackerEntries use ServerPlayerConnections instead of EntityPlayers as they did before. This caused the updateEntity to silently fail when removing the players from the trackedPlayers collection (of connections). This was resolved by retrieving the connections of the players before removing them from the list on 1.17+.
The getEntityTrackers method failed because it could not find any players for the same reason. This was resolved by retrieving the player from the connection before retrieving the Bukkit player from the EntityPlayer object when running on 1.17+.
- This fixesdmulloy2/ProtocolLib#1340
