Checkbox in button group not responding

    Details

      Description

      FULL PRODUCT VERSION :
      java version "1.5.0_06"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
      Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_06-b05, mixed mode

      ADDITIONAL OS VERSION INFORMATION :
      SUSE10 Pro, AMD64

      EXTRA RELEVANT SYSTEM CONFIGURATION :
      64 bit jdk 1.5.0_06

      A DESCRIPTION OF THE PROBLEM :
      Unselecting a JCheckBox button should turn off the check mark.
      ButtonGroup has a number of JCheckBox buttons. setSelected(button, false) should turn off the check if the JCheckBox button is selected?

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile the two classes and run PanelTest. Select a checkbox and then
      push the "Push Me" button. Select the same checkbox again and the checkbox is not unselected.

      Relevant lines of code (which I think
      should work but do not) are lines 74 - 78 of class PanelTest.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      check mark should be turned off when setSelected(button, false) is executed.
      ACTUAL -
      the check remains turned on indicating the button is still selected.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      CUSTOMER SUBMITTED WORKAROUND :
      ignore the problem but when focus has shifted to another JPanel I'd like to be able to uncheck the button
