> What if `JComboBox` uses a non-standard renderer which takes a property from an object? Let's assume, `JComboBox` is populated with `Rectangle` objects, a custom renderer is set which displays the value of the `bottom` field in the combo box. Your code, if I understand it correctly, will default to _full rectangle_ rather than what's really displayed.

You were right. At least in this case the current fix returns _full_rectangle_ dimension in a string form in stead of the text displayed in JComboBox. 
I think it is required to look for alternate fix, probably to get the displayed text from JComboBox and set it as an accessibleName.

I case of JTable and JList, the accessible context is of type JLabel which returns the accessibleName in string format.
