ah... 5.9.1 of the core spec: "The service registry must therefore ensure that bundles can only see services that are not incompatible with them. A service is not incompatible with the bundle getting the service when that bundle is not wired to another source class loader for this interface package than the bundle registering the service. That is, it is either wired to the same source class loader or it has no wire for that package at all." but I think Alan has a point that if you read the javadoc for ServiceReference.isAssignableTo() it does seem to apply a stronger rule: that is it returns true if both bundles use the same source for the package, otherwise false so if the bundle providing the service has a wire, and the bundle using the service doesn't have a wire, does that mean they use the "same source" for the package?
