At a high-level, you can think of jlink as doing something like this. It
can create a custom JRE image by taking the JDK, adding some additional
modules -- including your application(s), if desired -- and strip out
the modules you don't need.

Ah, I see the problem now. It seems you are trying to build JavaFX for
inclusion into an OpenJDK. That isn't the expected mode any longer now
that we have decoupled FX from the JDK, but it still should work. This
is a regression caused by my recent change to enable building the
standalone SDK. We no longer build the jdk.packager* modules in that
mode, and yet there is still a qualified export from javafx.graphics to
jdk.packager. This doesn't fail the FX build because we don't fail the
FX build on warnings.
I filed the following bug:
I'll fix it soon, but your workaround is to do what you've been doing
and use an Oracle JDK 10 build for as long as you need to build a JDK
using FX bits that you build. Ultimately, switching to jlink will likely
be the better solution for you.

The javapackager tool and associated jdk.packager and
jdk.packager.services modules have been removed from the JDK along with
JavaFX. They are not part of the standalone JavaFX builds.
