I am able to reproduce this exception using the following steps:

1. Create JFrame.
2. Change frame's layout to GridBagLayout.
3. Insert JPanel into the frame.
4. Ensure that panel's layout is Free Design.
5. Invoke Customize Layout action on the frame.
6. Right-click on the panel in the customizer
   => exception is thrown.
