You have given us the code, and some sample
output which doesn't fit your expectations,
but I'm left scratching my head as to what
you actually expect.  What are you trying to
do?  What does successful output look like?

Also, why is it necessary to dump the processed
text back into the same component?  Does it
make sense that the user could process some
text, and then press the button to process the
processed text?  (That's what this design suggests.)
Usually, input is separated from output.  Output
is usually set into a display component which
does not allow editing or processing.

Given that you are moving your Delphi based
code to Java, it might be a suitable moment
to reconsider this conflicting use of an
input area as an output device.  Here's
an alternative:



import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class SimpleTextEditorExampleFrame
     extends JFrame {

   JScrollPane scroller1 = new JScrollPane();
   JScrollPane scroller2 = new JScrollPane();
   JTextArea jTextArea1 = new JTextArea();
   JTextArea jTextArea2 = new JTextArea();
   JButton processButton = new JButton();
   GridBagLayout gridBagLayout1 = new GridBagLayout();


   public SimpleTextEditorExampleFrame() {
     try {
       jbInit();
     }
     catch (Exception ex) {
       ex.printStackTrace();
     }
   }

   void jbInit() throws Exception {
     this.getContentPane().setLayout(gridBagLayout1);
     processButton.setText("Process");
     processButton.addActionListener(
       new java.awt.event.ActionListener() {
         public void actionPerformed(ActionEvent e) {
           processButton_actionPerformed(e);
         }
       });
     jTextArea1.setText("");

     jTextArea2.setEditable(false);
     jTextArea2.setBackground(Color.lightGray);
     jTextArea2.setText("");

     this.addWindowListener(
        new java.awt.event.WindowAdapter() {
          public void windowClosing(WindowEvent e) {
            this_windowClosing(e);
          }
        });
     scroller1.getViewport().add(jTextArea1, null);
     scroller1.setPreferredSize(new Dimension(300, 150));
     scroller2.getViewport().add(jTextArea2, null);
     scroller2.setPreferredSize(new Dimension(300, 150));

     this.getContentPane().add(
       scroller1,
       new GridBagConstraints(0, 0, 1, 1, 1.0, 1.0,
         GridBagConstraints.NORTHWEST,
         GridBagConstraints.BOTH,
         new Insets(12, 12, 11, 11), 0, 0));
     this.getContentPane().add(
       scroller2,
       new GridBagConstraints(0, 1, 1, 1, 1.0, 1.0,
         GridBagConstraints.NORTHWEST,
         GridBagConstraints.BOTH,
         new Insets(0, 12, 0, 11), 0, 0));
     this.getContentPane().add(
       processButton,
       new GridBagConstraints(0, 2, 1, 1, 0.0, 0.0,
         GridBagConstraints.CENTER,
         GridBagConstraints.NONE,
         new Insets(12, 0, 11, 0), 0, 0));
   }

   public static void main(String[] args) {
     SimpleTextEditorExampleFrame frame =
         new SimpleTextEditorExampleFrame();
     frame.pack();
     frame.setVisible(true);
   }

   void processButton_actionPerformed(ActionEvent e) {
     try {
       jTextArea2.setText(jTextArea1.getText());
       jTextArea2.append("\n\n ----\n");
       jTextArea2.append(
           "Line count: " +
           String.valueOf(jTextArea1.getLineCount()) + "\n");
       jTextArea2.append(
           "Character count: " +
           String.valueOf(jTextArea1.getText().length()) + 
"\n");
       jTextArea2.append("----");
     }
     catch (Exception g) {
       jTextArea2.setText("\n Bad location exception occurred");
     }
   }

   void this_windowClosing(WindowEvent e) {
     System.exit(0);
   }
}
