Let me add another question to this discussion: As JavaFX 8 is now around (in addition to JavaFX 2.2), what will be the strategy to deal with the different JavaFX versions?
Up to now it seems the org.eclipse.javafx bundle exports the javafx packages with version constraints. As its a singleton, there will only be one org.eclipse.javafx bundle in an Eclipse installation, and for clients (with package imports) the available JavaFX version will thus depend on that bundle's package exports. However, org.eclipse.javafx is just a dummy bundle, so the version of the actually loaded JavaFX classes will IMHO depend on the JRE that was used to start the application (or whatever strategy the org.eclipse.fx.osgi fragment uses to locate them). How can you ensure that stays consistent? Doesn't it mean you will have to remove the version constraints from the org.eclipse.javafx bundle as soon as you are going to support multiple JavaFX versions (so the version will be decided at runtime when org.eclipse.fx.osgi loads the classes)? And wouldn't that imply that clients could also not specify version constraints on their package imports, because these could otherwise not be resolved? If this was the case, then would not the bundle's BREE be the right indicator for its required JavaFX version (as its done for all other JRE provided classes; of course implicating some support for JavaFX within the Execution Environment Descriptors)? Or does it mean for Mars there will only be an org.eclipse.javafx bundle that is bound to BREE 1.8 and exposes JavaFX 8 only (and there will be no support for JavaFX 2.2 and BREE 1.7)?
