BoxLayout cuts off large components

Name: jk109818 Date: 08/29/2003


FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
Large components are cut off when added to a boxlayout component. Several thousand lines of a text component seems to be the boundry.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a large JEditorPane (like 5000 lines)
2. Add the JEditorPane to a JPanel (any layout)
3. Add the JPanel to another JPanel (BoxLayout)
4. Add that JPanel to a JScrollPane in the content pane of a JFrame

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You should see all 5000 lines.
ACTUAL -
You see about 2000 lines

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.BoxLayout;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.GridLayout;
import javax.swing.JScrollPane;

public class BoxLayoutTester {

public void test(){
StringBuffer theContent = new StringBuffer();

for (int i = 0; i < 5000; i++)
theContent.append("This is line number " + i + ".\n");

JFrame theFrame = new JFrame("BoxLayoutTester");
theFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JEditorPane jep = new JEditorPane();
jep.setText(theContent.toString());
jep.setEditable(false);

// add the large editor pane to a JPanel with any layout
JPanel aPanel = new JPanel();
aPanel.setLayout(new GridLayout(0,1));
aPanel.add(jep);

// add the large JPanel to a box layout JPanel
JPanel boxLayoutPanel = new JPanel();
boxLayoutPanel.setLayout(new BoxLayout(boxLayoutPanel, BoxLayout.Y_AXIS));
boxLayoutPanel.add(aPanel);

theFrame.getContentPane().add(new JScrollPane(boxLayoutPanel));
theFrame.setSize(600, 600);
theFrame.setVisible(true);
}
    
public static void main(String[] args) {
BoxLayoutTester blt = new BoxLayoutTester();

blt.test();
    }
}
