      }});
    ct.setSize(500, 500);
    ct.setVisible(true);
  }
}

1. hightlight the text "bold, underline and italic" in the
   test program
2. click the bold, italic and underline buttons respectively
3. hightlight the text "old, under" click the bold button
4. hightlight the text "line" click the bold button

I'm assuming the text "line" should have changed from bold to
regular weight text. This problem seems to only happen when
the mark of the highlight occurs between a boundary of text which
has the attribute turned off and the attribute turned on.

orig synopsis: "wrong display of characters in a JTextPane on the screen and at printing"

Text cannot be bolded
if placed in a JTextPane with the Font Arial.
There is no error message, just no visible reaction.

The following example reproduces the bug in jdk1.2 and jdk1.3betha:
