Wrong Section, My Apologies.

I'm having a crash issue with Tab Completion on Online Players with a command. This is what was implemented, followed by a separate file named OnlinePlayers.java @Override public List<String> addTabCompletionOptions(final ICommandSender sender, final String[] args, final BlockPos pos) { return (args.length >= 1) ? getListOfStringsMatchingLastWord(args, OnlinePlayers.getListOfPlayerUsernames()) : null; } OnlinePlayers.java: package me.syns.slashping; import net.minecraft.client.network.*; import java.util.*; public class OnlinePlayers { public static String[] getListOfPlayerUsernames() { final String[] users = null; final Collection<NetworkPlayerInfo> players = Ping.mc.getNetHandler().getPlayerInfoMap(); final List<String> list = new ArrayList<>(); for (final NetworkPlayerInfo info : players) { list.add(info.getGameProfile().getName()); } return list.toArray(new String[0]); } } If you need anymore information, let me know. I've attempted various other methods and keep looking around as to why it's crashing. This is a mod being developed for 1.8.9, and soon to be ported to 1.12.2 (after I get some help regarding the Tab Completion)
