Preloader is not working with 8.1.2 plugin.

[Anvay-webonise]

we are using preloader for splash screen and its working perfectly fine with 2.0 plugin(with java 7) now with 8.1.2 (java 8) its not working.
.msi gets generated but splash screen is not working.

I had the same problem, but it seems that preloader is depracated in JavaFX 8 (or maybe only in the plugin, I don't know).
Have a look into:

Thanks @aliebelt.
JavaFx 8 supports for preloader https://docs.oracle.com/javase/8/javafx/api/javafx/application/Preloader.html
I think Its missing from plugin only.

I came across this issue myself, but its not an issue of this maven-plugin, its more a problem with the generated exe-file (which comes from javafxpackager). The problem is, as far as i understood the discussion, known but not really dealt with:
http://mail.openjdk.java.net/pipermail/openjfx-dev/2014-January/012296.html

But there is another thing i am confused with: when using mvn jfx:run the preloader is skipped, just by running the generated xyz-jfx.jar itself the preloader is executed.

This is closed, because its not handled within javafxpackager/native package app. Showing a splash-screen should be possible, but preloader are capable of more (http://stackoverflow.com/questions/15126210/how-to-use-javafx-preloader-with-stand-alone-application-in-eclipse).

I must admit, this is something very undocumented, but please re-open if you found an working example using native javafxpackager-tools.
