Java 11: Scenicview with efxclipse don't work (NoClassDefFoundError: javafx/scene/Node)

[ShawnKleese]

When i start Scenicview for Java11 to inspect a efxclipse RCP-App i'am getting this error in the console of my RCP-App.

Looks for some OSGI and JPMS Problems. Any Idea ?

The problem is that the InstrumentationImpl-Class uses

ClassLoader classLoader = ClassLoader.getSystemClassLoader(); Class c = classLoader.loadClass( ..., ...);

But the SystemClassloader does not know any of the openjfx classes..

I've looked in the fx.osgi-Module, if there is maybe some equal Problem solved...

One possibility could be to overwrite the systemclassloader with -Djava.system.class.loader=com.test.MyClassLoader Parameter.
(But i think this is ugly :-/ )

@tomsontom: Do you have another Idea ?

I need to give this a spin before I can give any advice
