try to replace %p and %p from a string

Hi all, i dont think this is a bukkit problem, but when i use the replace function to replace %k to the killers name, I get an error that i cant use that method again :S

This is what I use:

Code:

for (Player p : Bukkit.getServer().getOnlinePlayers())
                {
                    if (plugin.kills.containsKey(p.getName()))
                    {
                        String broadcast = plugin.getConfig().getString("language.death-message-broadcast");
                        String broadcast1 = broadcast.replace("%p", player.getName());
                        String broadcast2 = broadcast1.replace("%k", player.getKiller());
                        p.sendMessage(prefix + broadcast2);
                    }
                }

The second .replace gives this error, anyone who can help me?

 

What's the error? It could be several things...

 

player.getKiller().getType().name() firstly, also check if getKiller() is null.
