correct usage for @SuppressWarnings("unchecked")

I'm just going through and ensuring compilation with -Xlint and find
myself assuming that the cast will work -- which it currently does.
Should it be wrapped in a try/get? A more sophisticated use of
generics?

package view;

import database.*;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;

public class BeatlesLoader {

    private Logger logger =
Logger.getLogger(view.BeatlesLoader.class.getName());
    private ParametersBean mp = new ParametersBean();

    public BeatlesLoader() {
        logger.log(Level.INFO, "BeatlesLoader...");
    }

    @SuppressWarnings("unchecked")
    private List<Beatle> populateBeatles() {
        logger.log(Level.INFO, "populateBeatles...");
        database.DatabaseBean database = new database.DatabaseBean();
        ArrayList<ArrayList<String>> table = database.getTable();
        List<Beatle> beatles = new ArrayList<Beatle>();
        for (ArrayList record : table) {
            Beatle beatle = new Beatle(record);
            beatles.add(beatle);
        }
        logger.log(Level.INFO, "...populateBeatles" +
beatles.toString());
        return beatles;
    }

    public List<Beatle> getBeatles() {
        logger.log(Level.INFO, "getBeatles...");
        List<Beatle> beatles = populateBeatles();
        logger.log(Level.INFO, "...getBeatles" + beatles.toString());
        return beatles;
    }
}

thanks,
