Problem z MySQL w pluginie.

Cześć, mam taki kod umieszczony w dwóch klasach.

package pl.kchc.hardcorebans;

import org.bukkit.Bukkit;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class HardcoreBans extends JavaPlugin implements Listener {

	private DatabaseMySQL databaseMySQL;

	public void onEnable() {
		databaseMySQL = new DatabaseMySQL("localhost", "hardcorebans",
				"root", "");

		Bukkit.getServer().getPluginManager().registerEvents(this, this);
	}

	@EventHandler
	public void onPlayerDeath(PlayerDeathEvent event) {
		final String player = event.getEntity().getPlayer().getName();

		databaseMySQL.banPlayer(player, System.currentTimeMillis());
	}
}

package pl.kchc.hardcorebans;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class DatabaseMySQL {

	protected Connection connection;

	public DatabaseMySQL(String host, String base, String user, String password) {
		try {
			Class.forName("com.mysql.jdbc.Driver");
			connection = DriverManager.getConnection("jdbc:mysql://" + host
					+ "/" + base, user, password);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public String getBannedPlayer(String player) {
		try {
			PreparedStatement statement = connection
					.prepareStatement("SELECT uuid FROM `hardcorebans` WHERE uuid='"
							+ player + "'");
			ResultSet resultSet = statement.executeQuery();

			if (resultSet.next())
				return resultSet.getString("uuid");
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}

	public void banPlayer(String player, Long time) {
		try {
			PreparedStatement statement = connection
					.prepareStatement("INSERT INTO `hardcorebans` (uuid, time) VALUES ('"
							+ player + "', '" + time + "')");
			statement.executeQuery();
			statement.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

Wszystko fajnie, ale gdy gracz umrze wyskakuje błąd:
