This server is running CraftBukkit version git-Spigot-4520628-84676f3 (MC: 1.13-pre7) (Implementing API version 1.13-pre7-R0.1-SNAPSHOT)
When clearing the custom name of an entity (by passing null or an empty string), on 1.13 it will result in an 'empty' ChatComponent being used (instead of null/none). Resulting in a small, empty name tag above entities (instead of no name tag at all).
A fix might be to replace
if (name == null) { name = ""; }
with
if (name == "") { name = null; }
inside CraftEntity#setCustomName. And the name length checking would have to check for null then.
Reproduction plugin:
package de.blablubbabc.test2; import org.bukkit.Bukkit; import org.bukkit.Location; import org.bukkit.entity.Entity; import org.bukkit.entity.EntityType; import org.bukkit.event.EventHandler; import org.bukkit.event.Listener; import org.bukkit.event.player.PlayerJoinEvent; import org.bukkit.plugin.java.JavaPlugin; public class Test extends JavaPlugin implements Listener { public static Test INSTANCE = null; @Override public void onEnable() { INSTANCE = this; Bukkit.getPluginManager().registerEvents(this, this); } @Override public void onDisable() { INSTANCE = null; } @EventHandler void onPlayerJoin(PlayerJoinEvent event) { Bukkit.getScheduler().runTaskLater(this, () -> { event.getPlayer().sendMessage("Spawning mob"); Location loc = event.getPlayer().getLocation(); Entity entity = loc.getWorld().spawnEntity(loc, EntityType.VILLAGER); entity.setCustomName(null); }, 1L); } }
