In JTextField, JTextArea and JTextPane, executing Ctrl+Shift+O causes the cursor image to
stay in its original place. It will not disappear untill new cursor is put on top of it.

To reproduce bug:
Compile and run the following application.
Use Ctrl+Shift+O to change component orientation for any text component.
Note that cursor has stopped blinking
Use mouse to click anywhere inside any text component
Note that old cursor is still in its place
Use mouse to click on old cursor
Note that it is blincking again
Use mouse to click any where else
Note that old cursor disappeared
Use Ctrl+shift+O on another text component
Note that same problem occur
