Use any appliction with editable JComboBox with several items in it.
1) Launch JAWS (I used 15)
2) Start an app
3) Make JComboBox a focus owner.
4) Press down arrow. Item should be read correctly(e.g. "15 of 22").
5) press down( or up) arrow again. Now the selected item is read twice and its number in list is read incorrectly(previous selected item's number is read) (e.g. "15 of 22" instead of "16 of 22")

Regression: NO (I checked jdk1.7.0_07b10)
Platform specific: No
