This all sounds horrible - why do you have a whiteboard that is making reflective calls on remote service objects? If you *really* want to make this work then your best option would be to have the whiteboard implementation listen for remote service discovery events and to create a local bundle on the fly to consume each remote service. You can set the package imports correctly for each bundle, and have it expose the service object through another service inside the bundle.
It’s all pretty hacky though. Does your whiteboard really need the service instance (rather than just the service properties)? If the answer is yes then you really shouldn’t be using reflection to call it.
