> In case of JColorChooser, if one of the color dialogs is activated and the focus is on JRadioButton and “TAB” key is pressed to move the focus to next component, the focus is not moving to next component. The JRadioButton remains in the focus. Due to this, the accessibility is not working properly.

The problem is due to the way it creates the list of all the components in the container while deciding upon which component should be selected as focus owner on pressing the TAB key.
