  /* This test case brings up a TextArea in a scrollpane. For a particular width
   * and height(22, 51) setting of the ScrollPane, the application flickers viz. it toggles
   * between requiring to have a scrollbar and not requiring to have a scrollbar.
   *
   * this has been caused because, the width set for the TextArea does not exactly match
   * with size required for displaying some letters. calculateBreakPosition method returns
   * break position equal to the start position. It causes that number of lines necessary for
   * text displaying are calculated uncorrectly.
