Tested on windows, linux and it works ok. We showed the dialog at 
x+50,y+50 where x,y is the coordinate of the active window.
Do not have local mac system to test multimonitor setup.

Tested this case where window bounds is smaller than print dialog
but because of this check in ServiceUI.java

// if portion of dialog is not within the gc boundary
         if (!gcBounds.contains(dlgBounds)) {
             // put in the center relative to parent frame/dialog
             dialog.setLocationRelativeTo(owner);
         }

the dialog is shown in the primary window.
I saw we did not have this check for pageDialog(attr) where the dialog 
is shown in secondary monitor despite gcBounds smaller than print dialog.
Therefore, I removed this check from ServiceUI.
