[SOLVED] Probably Obvious

This code grabs a file and spits back a particular line. Or at least, that's what I want it to do. Any clue as to what might be going wrong? The files do exist, so it's not that. :-/

Code:java

public HashMap<Player, String> playerLang = new HashMap<Player, String>();
 
public String getLocalization(CommandSender sender, String key) {
        InputStream is = null;
        BufferedReader br = null;
        String line = null;
        try {
            if (sender instanceof Player) {
                is = getResource(getDataFolder() + File.separator + "locale_" + playerLang.get((Player)sender) + ".txt");
            } else {
                String language = Locale.getDefault().getLanguage();
                String country = Locale.getDefault().getCountry();
                if (getConfig().getBoolean("Language.override")) {
                    is = getResource(getDataFolder() + File.separator + "locale_" + getConfig().getString("Language.iso-code") + ".txt");
                } else if (isValidCode(language + country)) {
                    is = getResource(getDataFolder() + File.separator + "locale_" + language + country + ".txt");
                } else {
                    is = getResource(getDataFolder() + File.separator + "locale_enUS.txt");
                }
            }
            br = new BufferedReader(new InputStreamReader(is)); //line 228
            while ((line = br.readLine()) != null) {
                if (line.contains(key)) {
                    line = line.replace("\"", "");
                    line = line.replaceFirst("L\\[" + key + "\\] = ", "");
                    return line;
                    }
                }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

there are a lot cleaner ways of opening a *.txt file and use .readLine() to get your data...

Komak57 Turns out I didn't have my PlayerListener set up correctly, but thanks for the suggestion.
