 "Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1" is thrown.

To reproduce the bug:
Do the testing under Windows platform with arabic and Hebrew support

2. Go to the first JTextField
3. Select the text by pressing "Home+Shift+End" keys from the keyboard
4. Press the "BackSpace"
