When default and selected icon is set for JRadioButton, JCheckBox, JToggleButton etc in GTK LAF, the rest of the images are picked from GTK LAF. This creates improper behaviour for the component.

Once a custom default and selected image is set, the component should not load the other images from LAF. This will create inconsistency in UI.

This was working fine in 1.4.2. Its introduced in Tiger.
This behaviour can be noted in SwingSet demo -> DirectionPanel.java

Copy all files to a directory.
Compile and run attached CustomButtonGTKTest.java
Roll the mouse over the components, the component changes to default LAF settings. Refer to the attached screenshot.
