We have a rather complex application that needs as much screen real-estate as it can get, naturally the retina display Mac Books are excellent for this purpose.

To my knowledge this is not possible as of JDK 1.8. The only workaround is to detect retina and use the scale affine transform when drawing. However, detecting retina seems to be a problem since the only option that seems to be available isn't on a per monitor case which is probably not a good solution: How can I detect whether a Mac has a Retina display from Java?
