Isolating F helps with seeing the x.jar v1.0 first.
But that hides the CSL class.
Those jars should be able to see classes from A-E, if they are not .war classes.
Ah, direct streams, it always helps. :-)
Hopefully I'll find some more time soon to check how to do proper solution.
I will have to be "OSGi"-like in order to work w/o hacks.
