In fact you ARE doing the things explained in Paul Bakker’s article. Or rather,
Karaf does them for you: it sets up the system bundle exports using the
contents of jre.properties.
By default Felix (and all other OSGi frameworks that I’m aware of) exports only
the JavaSE standard packages. JavaFX is not part of JavaSE standard, therefore
it is not exported by default. Somebody has to add its packages to the system
bundle exports — you can do this yourself with a single line of code, or you
can drag in all the dependencies of Karaf. I know which I would choose.
