JComboBox selected item is not read by NVDA if action listener is added to it, and inside listener perform selection in another component(e.g. another combobox). Another component is read perfectly, but current selection in currect component is unknown for user.
I tested with 2 JComboboxes.
Try an attached jar.
Not a regression (7u7 also does not work)
I have tested 7u75b10 32 bit & NVDA 32 bit.
