The demo test:
--------------------------------------------------
import javax.swing.*;
import java.awt.event.*;
import java.beans.PropertyChangeListener;

public class Test {

    public static class FakeJToolBar extends JToolBar {
        public JButton createActionComponent(Action a) {
            return super.createActionComponent(a);
        }
    }

    public static class FakeAction implements Action {
        
        private String name;
        private Icon icon;
        private String short_description;
        private boolean isEnabled;
        
        public FakeAction(String name,
                          Icon icon,
                          String short_description,
                          boolean isEnabled) {
            this.name = name;
            this.icon = icon;
            this.short_description = short_description;
            this.isEnabled = isEnabled;
        }
        
        public Object getValue(String key) {
            if (key.equals(Action.NAME)) {
                return name;
            } else if (key.equals(Action.SMALL_ICON)) {
                return icon;
            } else if (key.equals(Action.SHORT_DESCRIPTION)) {
                return short_description;
            } else {
                return null;
            }
        }
        public void putValue(String key, Object value) {}
        public void setEnabled(boolean b) {isEnabled = b;}
        public boolean isEnabled() {return isEnabled;}
        public void addPropertyChangeListener(PropertyChangeListener listener) {}
        public void removePropertyChangeListener(PropertyChangeListener listener) {}
        public void actionPerformed(ActionEvent e) {}
    }

    public static void main(String argv[]) {
        Icon icon = new ImageIcon();
        String short_description = "short_description";
        boolean isEnabled = true;

        FakeAction action = null;
        JButton button = null;
        String name = null;
        FakeJToolBar jtb = new FakeJToolBar();

        name = "test";
        action = new FakeAction(name, icon, "", false);
        button = jtb.createActionComponent(action);
        System.out.println(""+name+" -> \""+button.getText()+"\".");

        name = "";
        action = new FakeAction(name, icon, "", false);
        button = jtb.createActionComponent(action);
        System.out.println(""+name+" -> \""+button.getText()+"\".");

        name = null;
        action = new FakeAction(name, icon, "", false);
        button = jtb.createActionComponent(action);
        System.out.println(""+name+" -> \""+button.getText()+"\".");
    }
}

Output:
--------------------------------------------------
test -> "test".
 -> "".
null -> "".
