When using jdk-9+153 to build javafx.* modules, we get build failures because javac doesn't load required modules into the module graph in some cases. That bug is tracked as JDK-8172809.

In order to not be blocked from upgrading to a later compiler, we should look for a workaround in build.gradle by adding the modules that javac is otherwise unable to load. This will be done using "--add-modules" arguments.
