The following works for me (no exception):

import java.awt.event.*;
import javax.swing.JButton;

class Test {

    public static void print(ActionEvent e) { 
System.out.println("Hello!"); }

    public static void main(String[] args) {
       final ActionListener al4 = Test#print( ActionEvent );
       JButton b = new JButton();
      b.addActionListener(al4);
      b.doClick();
      b.removeActionListener(al4);
   }
}

Is it close enough to your test case?
