Because we (Oracle) have very strict rules about publishing
binaries. We are not allowed to publish anything that hasn't been
approved for release, even an experimental test program.<br>

While that might be easier, it is not possible for us to provide
such a binary.<br>
<br>
We could simplify it a bit by providing instructions to download
the JMODs (rather than the SDK) from jdk.java.net/direct3d12 and
use jlink to create a JDK that includes JavaFX. That way the
custom options only need to be added one time to jlink; running
"javac" and "java" would need no options related to finding the
JavaFX modules or enabling native access.<br>

<p>I will have to check whether I have time to look into this,

<br>
Isn't this where something like jlink could easily solve all
these steps and the user would just have to run one of
multiple launcher scripts of a prebuilt runtime image? I
would argue it would be faster to just build a jlink image
and provide a download link compared to writing the detailed
instructions so that users run the test exactly as they
should.</p>
