I have every Oracle JDK and OpenJDK version from 8 and above installed. 
I had assumed that Oracle JDK(s) were required because they were the 
only ones that would work as OpenJDK 9 and 10 builds in Arch Linux don't 
support JavaFX and using a self compiled JDK 11 isn't possible due to 
that bug.

I'm using Gradle 4.7 and Oracle JDK 10 to build.

So like it was done with OpenJDK 8 overlay but just with modules 
instead, basically?

Arch Linux uses the rolling release update model, so it usually gets the 
newest software before any other Linux distro.

Removing -Werror from those two lines got me a compile, though with many 
more warnings. However, attempting to compile an OpenJDK with JavaFX 
results in its own build fail due to jdk packager module being missing 
in the JavaFX build. See:

I tried copying the modular src files from a previous build and pasting 
them into the new one that doesn't have it and now I just get a build 
fail saying that JDK packager is marked for deprecation. I take it JDK 
Packager is in the process of being removed then?
