JFileChooser added to a JFrame similar to the example also works, I guess it's
because frame is made inaccessible. But when we try to disable JFileChooser
alone, it's not working because we need to disable each sub-component in which
JFileChooser is made up of. As per debugging I found out that peer component is
showing null for JFileChooser.disable whereas for JFrame the disabling is taken
care by peer component in Component class.
