JFX as an OSGi service?

[Stephen Winnall]

Anirvan, Kevin

Thanks for this.

I’m an expert neither in JavaFX nor in OSGi, but I think the basis of the JavaFX/OSGi incompatibility is control. To work with OSGi, JavaFX has to relinquish control of its startup sequence to OSGi in such a way that javafx.application.Application (or its proxy) is instantiated by OSGi and submits to OSGi’s bundle/service lifecycle. AN OSGi expert can probably formulate this better…

Platform.startup(runnable) /might/ do it. Platform.launch(class) doesn’t because the object thereby instantiated is always under the control of JavaFX - and thus not of OSGi.

I’m not comfortable using JFXPanel: if I wanted to use Swing I wouldn’t be trying to use JavaFX. But thank you for the hint.
