CEF currently targets JDK8 which will exit support in January 2019. At this point we're thinking about moving to JDK11 which released this month (September), and then tracking the JDK version more closely going forward (updating approximately every 6 months with the new JDK release). One nice feature that we should get with newer JDK versions is proper DPI awareness (e.g. detecting high-DPI displays on macOS and Windows).
