<AWT Dev> <Swing Dev> [12] JDK-7124285: Nothing heard from VoiceOver regarding the status of the progress bar

Hi Krishna, Shashi,

I wonder how native progress bars behave. Is their value read by 
assistive technologies? Are they focusable? Are they focusable if no 
assistive technology enabled?

JLabel is not focusable. It does not accept user input directly. Are 
JLabels also skipped by assistive technologies?
If setLabelFor(Component) is called, the label is associated with a 
component. Is label read when the associated component is focused?
