Use the arrow keys to change the default values in a JComboBox. Hitting Esc unposts menu, but the selected item changes to the item where the Esc key was hit. 

N/A

This is not a bug.  The behavior is the same as Win32 combo boxes.

This is not a bug. Combo boxes in Windows behaves the same. In fact, the JComboBox has been implemented like this since the inception of Swing. In fact, we will not change the semantics of the escape key at this stage in the development of Swing because it will break a lot of applications. 

I was looking for the Accessibility keybindings spec but I couldn't find it. I was looking at http://accessiblity.eng and the online Java Look and Feel Design Guidelines but couldn't find anything specifically about keybindings and accessibility. I even did a Google search and didn't turn up anything specific.
