<Swing Dev> Unable to view focus in Non-Editable Text Area

[Sean Chou]

Hi all,

I found a similar bug was reported for JTextArea.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4512626

That bug is about JTextArea, while this is about TextArea behavior
difference.

It seems showing a caret is a general way to address this kind of
accessibility.
So I made a simple patch.

             getComponent().repaint();
