When the user selects Choice item or menuitem , that falls on the textarea, leaves their impression on the border of the textarea.

Step to reproduce:
---------------------
1) Run the attached program.
2) Click on the textArea.
3) Click on the Chioce & select any item. Observe that top right most border of the textarea is having a painting issue.
4) Click on the menu & select any menuitem. Observe the right most boder of the textarea is having a painting issue.
If you see the same then the bug is reproduced. I have attached the screen shots of the same.
This works fine jdk/1.5.0/fcs/b64/ & Mustang b20 , but failes from Mustang b25 to b90.
