Using Swing pre-1.0 (/usr/local/java/swing-pre-1.0) and JDK 1.1.5.

setBackground() does not have any effect on JCheckBox and JRadioButton.
This functionality used to work correctly in Swing 0.7.

The following example attempts to set the background color of 
JButton, JCheckBox, and JRadioButton.  Only JButton has the expected
background color.

   I want to add some information to the description:
JLabel has that problem with background color, too,  even in metal.
I was using swing-1.0.1.
