FULL PRODUCT VERSION :
java version "1.8.0_40"
Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Windows 7 Enterprise, Service Pack 1
A DESCRIPTION OF THE PROBLEM :
Using TAB to navigate to next radiobutton in buttongroup will cause:
java.lang.IllegalArgumentException: aContainer is not a focus cycle root of aComponent
When using WindowsLookAndFeel via:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
The NimbusLookAndFeel handles this without problem. Other look and feels also will produce this problem.
REGRESSION. Last worked in version 8u31
ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
We have a JFrame containing a JDesktopPane.
We add a JInternalFrame, holding a ButtonGroup with three JRadioButtons, to the JDesktopPane.
When using TAB to navigate to next button we get:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: aContainer is not a focus cycle root of aComponent
In the case we use WindowsLookAndFeel via:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
The NimbusLookAndFeel handles this without problem. Other look and feels also will produce this problem.
Se source code for executable example.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The next radio button should gain focus.
ACTUAL -
java.lang.IllegalArgumentException: aContainer is not a focus cycle root of aComponent
No navigation is executed.

CUSTOMER SUBMITTED WORKAROUND :
Currently we have no workaround for using TAB to navigate, the user is forced to use mouse to navigate to next radiobutton.
This will not stop development but will inconsistent behavior to end user.
Could this one be causing:
