You may wish to try to isolate the minimal code required to demonstrate the problem and the precise conditions as well. I'd also search the Java bug database to see if it's been reported. If not, and others can reproduce the problem, you may wish to report a bug yourself.

Hi ,

Please find below the code snippet to reproduce the problem.

import java.awt.Dimension;

import javax.swing.*;

public class Test{

    public JPanel createContentPane (){

          JPanel totalGUI = new JPanel();
        
        // This is the text to be stored in Jtextarea.
        String story =       "Testing JtextArea Text\n\n"+
         "data gets corrupted when there is huge amount of data\n\n"+
         "The Internet Foundation Classes (IFC) were a graphics \n\n"+

        // We create the TextArea and pass the textarea in as an argument.
        JTextArea storyArea = new JTextArea(story);
        /*setEditable is set to true so that we can add more text into it for testing*/
        storyArea.setEditable(true);
        storyArea.setLineWrap(true);
        storyArea.setWrapStyleWord(true);
        
        /* We create the ScrollPane and instantiate it with the TextArea as an argument*/
        // along with two constants that define the behaviour of the scrollbars.
        JScrollPane area = new JScrollPane(storyArea, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
                                           JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
        
        // We then set the preferred size of the scrollpane.
        area.setPreferredSize(new Dimension(300, 200));
        
        // and add it to the GUI.
        totalGUI.add(area);
        totalGUI.setOpaque(true);
        return totalGUI;
    }

    private static void createAndShowGUI() {

        JFrame.setDefaultLookAndFeelDecorated(true);
        JFrame frame = new JFrame("[=] Embrace of the JScrollPane [=]");

        Test demo = new Test();
        frame.setContentPane(demo.createContentPane());
        
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(350, 300);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

I have set textarea editable property to true.
So to reproduce the problem run above program on Solaris System and then copy the text in story string around 50 times in textArea.The data will be corrupt.

Thanks,
Simmi

Hi,

It seems it is a bug.Can anyone suggest me the workaround for this.
Wherein I can use some other component to display huge amount of data along with the scroll bars.

Thanks,
