The point is you can't require two different bootJDK versions. As Jon
said as soon as someone relies on a JDK 10 feature** you can no longer
use a JDK 9 boot JDK.
** This isn't quite as broad as it sounds. Only critical bootstrapping
parts of the build are limited to the capabilities of the bootJDK. The
other parts will be built with the interim javac.
