I believe at the moment the blueprint api bundle is exporting org.osgi.service.blueprint, and the core bundle is also exporting it at version 1.0.0. (the all-in-one bundle is too, but I'm less worried about it)
I think the relevant part of the spec is 121.13.5: To mitigate type incompatibility problems, a Blueprint extender must export the org.osgi.service.blueprint package. In the uses: directive, it should list any packages of classes that can be shared between the Blueprint extender and the Blueprint bundle. Blueprint bundles should import this package. I think this means 1. the api bundle should not export this package 2. the core bundle should have a big uses clause. I'm not sure what should be in the uses clause. All the exports from the core bundle? Obviously fixing this is trivial once we figure out what to do :-) thanks david jencks
