Yes Jeremias, I think what you've done is very close to what I'm looking for. I think the restlet team is doing something kinda like this too [1]. I'm working with other teams which use jar SPI (they are kind enough to make their stuff bundles, but don't care about OSGi beyond that point), and I want a generic way of loading impls. The dynamism obviously wouldn't be there, so I was thinking that the appropriate level of bundle state required would merely be INSTALLED. I started reading through your code and documentation. I was wondering if it handles all the scenarios where a bundle can be updated, installed, uninstalled. I was hoping to accomplish this generic lookup without requiring a special manifest header, but I see how that introduces all sorts of complexities for the implementation (even with BundleTracker and PackageAdmin).
