   There is a way to load system images and icons on MacOS X in Java by 
using: Toolkit.getDefaultToolkit().getImage("NSImage://NSImageName") method:
https://developer.apple.com/library/mac/documentation/java/conceptual/java14development/04-JavaUIToolkits/JavaUIToolkits.html
    This method calls [NSImage imageNamed: "NSImageName"] and we are 
going to reuse it for the system icons loading.

    There is the fix that has been recently sent to review: 
http://mail.openjdk.java.net/pipermail/awt-dev/2013-October/006133.html
     A user needs to override the getScaledInstance(width, height, 
hints)  method in Image class and returns images with necessary 
resolution according to
     the given width and height.  Images with @2x postfix should be 
automatically loaded into the ToolkitImage on MacOS X.

   Thanks,
