On Windows, HiDPI screens are supported from JDK 9 and upwards; on MacOS it might have been introduced earlier (not sure).
On Java versions that do not support HiDPI screens, the splash screen should show up in low resolution, like before. I have confirmed this on JDK8 on Windows (I don't have a Mac to test).
The way this works is that the splash screen PNG is now double resolution, but resized to 50% (to SPLASH_WIDTH*SPLASH_HEIGHT logical pixels) via a transform on the paint method's Graphics2D object. JDK versions that support HiDPI will in turn apply its own transform to scale the image back up to a higher device pixel resolution.
