      A DESCRIPTION OF THE PROBLEM :
      When using a JTextArea with right-toleft text (arabic) the text area does not perform line wrapping on a character boundry and instead always uses the word boundries.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run the demo program provided. When the frame opens notice that the text area is wrapping at word boundries instead of character boundries.



      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The text area should wrap at character boundries.
      ACTUAL -
      The text area wraps on the word (spaces).

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      No error is reported.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      import java.awt.Font;

      import javax.swing.JFrame;
      import javax.swing.JScrollPane;
      import javax.swing.JTextArea;

      public class JTextAreaBidiCharWrapError

              super("JTextArea Bidi Character Wrap Error");
              
              // Turn line wrap on but wrap on word off.
              // Insert some text including an Arabic Alef
              // to force the JTextArea into "I18N" mode.
              // Note that the display does wrap on
              // word boundries instead of character boundries.
              // (I use a monospaced font to make the display
              // easier to see the wrapping is on words and not
              // characters.)
              textArea_.setFont(
                      new Font("Monospaced", Font.PLAIN, 14));
              textArea_.setLineWrap(true);
              textArea_.setWrapStyleWord(false);
              textArea_.setText(
               "alef-\u0627- abcde fghij klmno pqrst uvwxy z\n" +
               "\n");
              
              getContentPane().add(new JScrollPane(textArea_));
