After looking through native macOS apps, the only one found is in System Preferences > Date & Time. The problem here is that the native equivalent found here uses a blue button with a single down arrow as the button's symbol. The current swing implementation uses a white button with an up & down arrow symbol for the button. A JRS widget button that has this blue button with a single downward arrow exists but does not support text fields.

I looked through Apple's documentation for these UI elements but editable JComboBoxes aren't specifically listed anywhere. Similarly, there's barely any editable JComboBoxes used in native mac apps (only the date & time). So, I don't think it's a major issue if JComboBox does not exactly match the example found in Date & Time.
