In this test, we set frame as null and passed it on as a parameter to
Toolkit.getPrintJob( Frame, String, JobAttributes, PageAttributes ).
We also pass jobAttributes as null and set the DialogType as NATIVE.
The test is still passing in solaris although it throws IllegalArgumentException
in windows. Based on the documentation for jdk1.3, the behavior in solaris is
unexpected.

The test file is paste below:

import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;

public class nullFrame extends Frame implements ActionListener {
    //Declare things used in the test, like buttons and labels here
    private Button print;
    private JobAttributes jbattrib;
    private PageAttributes pgattrib;
    boolean excepThrown = false;
    
   public nullFrame() {
    this.setLayout(new FlowLayout());
        print = new Button("Print");
        print.addActionListener(this);
        add(print);
        setSize(200, 100);
        setVisible(true);
   }
   
   
    public void actionPerformed(ActionEvent e) {
        
        if(e.getSource() == print) {
            Toolkit tk = Toolkit.getDefaultToolkit();
            jbattrib = new JobAttributes();
            pgattrib = new PageAttributes();
            
            //set the dialog type to Native
            jbattrib.setDialog(JobAttributes.DialogType.NATIVE);
            try {
if(tk != null) {
         PrintJob pjob = tk.getPrintJob(null, "Printing Test",
                                                        null, pgattrib);
                if(pjob == null) {
                 System.out.println("PrintJob Not Created");
                 }
else {
         pjob.end();
                 }
             }
            }catch(Exception excep) {
             System.out.println(excep.toString());
             excepThrown = true;
            }
          if(!excepThrown)
            throw new RuntimeException("IllegalArgument Exception is not thrown when frame is set to null");
        }
    }
    
    public static void main(String[] args) {
