Since the a11y APIs are called upon the `AquaComboBoxButton` (subclass of JButton) instance, need to set the text of the button to current displayed text of JComboBox. JComboBox contains `getAccessibleName` method but it is not invoked.

Yeah, it worked for editable JComboBox. For editable JComboBox, the string is returned by NavigableTextAccessibility and it returns the current text displayed in editor.
