I'm not entirely sure, going through this process myself. I would expect that openjfx.jar contains only the open bits, so that you would be free to redistribute it as you see fit subject to the GPLv2 w/classpath exception. If it combined our binary plug stuff then you'd not be able to redistribute it.

So that would suggest you must prepend openjfxrt.jar onto the boot class path BEFORE jfxrt.jar or your modifications won't get picked up.
