If two separate AbstractButton objects are both selected,
and both are added to the same ButtonGroup object, they will
both continue to be selected after the addition to the group.
The ButtonGroup class currently checks for selectedness in
the add(AbstractButton) method, so I'm assuming the problem
is in the ButtonModel.setGroup(ButtonGroup) method.

  Here is some trivial code to demonstrate:

JRadioButton buttonOne = new JRadioButton("one", true);
JRadioButton buttonTwo = new JRadioButton("two", true);
ButtonGroup group = new ButtonGroup();
group.add(buttonOne);
group.add(buttonTwo);
// Both buttons are selected at this point

  The old behavior in 1.3 seemed to be to retain the first
button that is selected as the selected button when others
are added.

Release Regression From : merlin-beta3
The above release value was the last known release where this
bug was knwon to work. Since then there has been a regression.
