But I would have to know the bundle that TransactionManager comes from in
order to listener to it, no?
Doable. In OsgiServiceUtil, look at its use of ServiceTracker. Instead of
ServiceTracker#getServices, we'd use ServiceTracker#getServiceReferences. From the
returned ServiceReference, we can get both the actual service impl, as well as the Bundle
that provides it.
