Details:

Steps to reproduce:
1. Compile and run the attached testcase.

Expected results:
1. A window with textarea shows up. Lines 0-18 and vertical scroll bar are
visible. (Sun's jdk shows horizontal scroll bar too but that is unnecessary.)

Actual results:
1. A window with textarea shows up. Lines 0-20 are visible but there are no
visible scroll bars.

Testcase:
import javax.swing.*;
public class testcase extends JFrame {
        public static void main(String[] args) {
                new testcase().show();
        }
        public testcase() {
                JTextArea area = new JTextArea(20, 45);
                JScrollPane scrollpane = new JScrollPane(area);
                this.setContentPane(scrollpane);
                this.pack();
                for (int i=0; i<80; i++) {
                        area.append("line#" + i + "\n");
                }
        }

}

Note that if you resize the window then vertical scroll bar is shown
correctly.
