Constructors of all descendants of JComponent dump core in headless
mode. This is true for jdk1.4-beta40,44,45. See example:

---Test2.java:
import javax.swing.*;

public class Test2 {
    public static void main(String[] args) {
        new JToolBar();
        //you can write here any JComponent descendant
    }
}
