From all the documentation I find, I understand that even though with Java packager you can create an executable including the (required parts of the) JVM, you still need to unpack and repack all the jars into a single jar. This has the problem of breaking signed jars. Classloader based solutions like onejar get into all kind of conflicts with possible other classloaders in the application.
It would be a major improvement (not only for JavaFX applications, but also standalone servers) if it would become possible to create a truly single distributable, without having to repack the jars. So either by automatic unpacking to a tmp and setting the classpath prior to stating java (cleaning up afterwards), or allowing jars-in-jars or jars-in-distributable.
Just my 2 cents,
