JDK-8153350 - JavaFX webstart with javaws.exe selects wrong toolkit (unnecessary relaunch)

Let me try that again...

There are some properties passed to the VM (by dtjava.js) that change the default toolkit, but those would only be relevant for web deployment. Java Packager does produce html and JNLP files so it's possible that's what it's for.

Actually, you can pass -J-Djnlp.tk=jfx to javaws and it will start with the FX toolkit and avoid the relaunch.
