Starting with Java 9, and the introduction of the module system, the JavaFX modules are now an integral part of the runtime environment for the desktop. Because of this tie, there is currently no provision or capability for the output of the OpenJFX 9 or later build to be used as an overlay. It is still possible however to develop and enhance OpenJFX, and use that result to build an OpenJDK. (Recheckstill relevant?)
We are exploring making this easier, by enabling a developer to build a set of javafx.* modules that can be used with a clean OpenJDK build (without the javafx.* modules). Stay tuned. (Seems completecompleted?)
