@azuev-java We have a ItemListener for JComboBox defined in AquaComboBoxUI here to handle any changes in combobox selected item.

https://github.com/openjdk/jdk/blob/9e6cb620486ac7b0adaefeb2000babf3ea31207f/src/java.desktop/macosx/classes/com/apple/laf/AquaComboBoxUI.java#L135

Tried setting the `accessibleName` for arrowButton in `itemStateChanged` method. So whenever combobox value  changes using list selection, **accessibleName is set to the selected Item**.

For initial accessibleName, it can be set to the first value of data model inside `AquaComboBoxButton constructor` code.

`However, this doesn't work with custom renederer.`
