Hi Prasanta,
With the DefaultButtonModel we can get the same exception if a custom
implementation of the ButtonModel is used.
So, it is better check whether the model is a DefaultButtonModel and
skip if grouping is not supported. Or, perhaps, it is reasonable to pull
up the getGroup() into the ButtonModel interface which already has
setGroup().

Hi All,
Please review a fix for an issue where a crash is reported when focus
is moved with custom ButtonModel.
Issue was in LayoutFocusTraversalPolicy, the ButtonModel was wrongly
typecasted to JToggleButton when the button model is
DefaultButtonModel, resulting in ClassCastException.
Proposed fix is to cast to super class DefaultButtonModel and then
check for JToggleButton member.
