Write a regression test for JDK-4390885 Enhancement Request.
Issue:
Please add the ability to set the location of a JFileChooser. This might be a
bug, but JFileChooser.setLocation() has no effect when
JFileChooser.showXXXXDialog() is called. This is becoming very important as the
popularity of multiple monitors is increasing. These dialogs show up on the
wrong monitor which is really annoying. Also due to bug #4189244 I am unable to
avoid painting problems by positioning the dialog away from the menu item that
initiated it.
Fix:
Now it's possible to set the location of Dialog in JFileChooser.
Testing:
1. Tested in Mach5 10 times per platform(macos,linux,windows) and got all Pass.
