that returns the string

Answer 1

It appears that OptionPane.okButtonText is a feature unique to Aqua available in all L&Fs, as shown using this approach that includes localized values not seen when iterating over the entrySet().

import javax.swing.UIDefaults;
import javax.swing.UIManager;

/** @see https://stackoverflow.com/questions/5729306 */
public class OptionPaneDefaults {

    public static void main(String[] args) throws Exception {
        UIManager.LookAndFeelInfo[] lfa =
            UIManager.getInstalledLookAndFeels();
        for (UIManager.LookAndFeelInfo lf : lfa) {
            UIManager.setLookAndFeel(lf.getClassName());
            UIDefaults uid = UIManager.getLookAndFeelDefaults();
            System.out.println("***"
                + " " + lf.getName()
                + " " + lf.getClassName()
                + " " + uid.size() + " entries");
            String ok = "OptionPane.okButtonText";
            String text = "";
            text += " LAF: " + UIManager.getLookAndFeelDefaults().get(ok);
            text += " lookup: " + UIManager.get(ok);
            text += " default: " + UIManager.getDefaults().get(ok);
            System.out.println(text);
        }
    }
}
