I think I could create an annoted class through Clojure.
But still, it wouldn't be "ready to be read" from the bundle
jar/directory on the filesystem.
So I would still have to find a way to dynamically hook into the
mechanism so that I can load a class instance ...

... so I really hope that this extension you're talking about is working.
Since my plugin will work within the regular Eclipse IDE, I'm not sure
I should push my own IContributionFactory replacing / superseding the
Eclipse's ReflectionContributionFactory.
I saw the extension point you're talking about. It's
IContributionFactorySpi, right ? Provided via the
org.eclipse.e4.languages extension point.
Why do you say you doubt it's still available/working?
