The JButton inside a popup is not getting the focus after first mouse click. This happens in Solaris Sparc machines and is not happening in Windows platforms.

Step to reproduce: Click the button that pops out on running the following program.

Hardware & OS in which testing done: Ultra 10 & OS ver 5.7

Code to reproduce:
import java.awt.*;
import javax.swing.*;

public class poptest01 {
  JLabel label;
  JButton button;
  
  public poptest01() {
    button = new JButton("Hello, World!");
    button.setBackground(Color.green);
    button.setToolTipText("it is a button!");
    
    PopupFactory factory = PopupFactory.getSharedInstance();
    Popup popup = factory.getPopup(null, button, 100, 200);
    popup.show();
    /*try {
      Thread.sleep(2000);
    }
    catch (InterruptedException ie) {
      ie.printStackTrace();
    }*/
    //popup.hide();
  }
  
  public static void main(String args[]) {
    poptest01 s = new poptest01();
  }
}

More info:
The button is not getting the dotted rectangle around the button name, which indicates that the button indeed has the focus.
