JSpinner buttons do not paint focus border on Java 7

Create a spinner around a text field
When the text field is focused the field and the buttons are sourrounded by a 
blue border. On Java 7 the border only surrounds the field but not the spin 
buttons.

This seems to happen on all platforms.
It seems the painter for the buttons is not selected correctly. It always 
selects the
background painter and not the background-selected painter.

This needs further investigation what is going wrong here.
