I should be available on IRC this Friday or next week. I'm a bit busy this week at an OSGi F2F meeting.
I imagine you will need to have a framework extension bundle for JavaFX that defines the packages that need to be exported from the javafx namespace. If such a bundle is installed using p2 I think you can associate a configuration unit that defines the configuration osgi.frameworkParentClassloader=ext must be set for the installation. So for the Java 8 execution environment profile we would not include the javafx packages as exported automatically by the system bundle. Instead additional configuration of the framework is required in order to make the use of the extension class loader and export the javafx package. I can think of some other rather nasty hacks that could be done by using equinox framework hooks. But I would like to avoid such hacks.

The problem is that people might use it in an existing OSGi app like the Eclipse IDE and there we probably should and can not modify it. The really problem is caused by Oracle but i'd really don't want to suffer our users from it. Do you have time for an IRC session this or next week to discuss possible solutions?

This should allow the system bundle to export the packages available on the extension class path.

My current concerns are the future. First of all JavaFX 8 although shipped with Oracle-JDK8 will not be JSRed so its packages can not get part of the Java8 profile. It currently looks like they are not getting on the bootclasspath but rather pushed into lib/ext. I've done some tests today and it looks like this lib/ext stuff is going give us some headaches because this means the javafx stuff is not going to be on the bootclasspath which the system.bundle delegates to, am I right with this? So what could be a runtime-solution? Would a OpenJDK8-Profile which exports JavaFX packages help us, or would it ran into the same problem that it will delegate to the bootclassloader whereas we'd need to consult the extension-classloader? Once we figured out how we can solve the problem at the runtime layer we can go the next step to tweak PDE in a way that it we can work with it.
