Hey there, I updated my plugin to 1.9.4 which was still on 1.8. Now i have issues with the tablist. Code (Text): public void sendHeaderAndFooter(Player player, String head, String foot) { head = "§aWillkommen auf MineGame-mc.de"; foot = "§aminegame-mc.de"; PlayerConnection connection = ((CraftPlayer) player).getHandle().playerConnection; IChatBaseComponent header = IChatBaseComponent.ChatSerializer.a("{'color':'', 'text':'" + head + "'}"); IChatBaseComponent footer = IChatBaseComponent.ChatSerializer.a("{'color':'', 'text':'" + foot + "'}"); PacketPlayOutPlayerListHeaderFooter packet = new PacketPlayOutPlayerListHeaderFooter(); try { Field headerField = packet.getClass().getDeclaredField("a"); headerField.setAccessible(true); headerField.set(packet, header); headerField.setAccessible(!headerField.isAccessible()); Field footerField = packet.getClass().getDeclaredField("b"); footerField.setAccessible(true); footerField.set(packet, footer); footerField.setAccessible(!footerField.isAccessible()); } catch (Exception e) { e.printStackTrace(); } connection.sendPacket(packet); } Issue: Spoiler org.bukkit.event.EventException at org.bukkit.plugin.java.JavaPluginLoader$1.execute(JavaPluginLoader.java:310)

You need to update your imports. Since your not using reflection of is version specific for the version of imports you are using
I know it's an old thread but could I bump this? :/ I'm having the exact same issue and I can't find a solution anywhere else.
Already figured it out: For people looking at this thread, go and make sure that you're using the right methods for 1.9, 1.10, and/or 1.8. My plugin has a method to check what version the server's running and create a tab message in the specific manner for that version. If you want code for this, message me at www.minedrix.com/profile/5222917
