Steps:
1) Open java Control Panel
2) Go to the Java tab
3) Click on any view button (there are two view buttons)
4) Click on Find -- > Next
5) A JRE Finder window comes up

The window is a File chooser but the actual intention here is, the user should choose a direcroty or a Drive to find all the JREs in it and not any file.

So it is better to user a Directory chooser (see the attachment) instead of FileChooser (not to confuse the user)
