I want to listen ItemSpawnEvent but the event never triggers. Also i tried EntitySpawnEvent but i couldn't trigger it too. Event above, triggering successfully. i tried 4 different spigot fork and 2 different spigot versions. i tried different priorities. no one solved this.

My tries:

1. break a chest (contains items)
2. drop manually (with q button)
3. dropNaturally() method
   # drop() method
4. kill a mob

	@EventHandler
	public void onPlayerDropEvent(PlayerDropItemEvent e) {
		Bukkit.broadcastMessage("PlayerDropItemEvent");
                //works
	}


	@EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = true)
	public void onItemSpawnEvent(ItemSpawnEvent e) {
		System.out.println("tttt");
		Bukkit.broadcastMessage("1");
                //not works
}
