Guillaume Nodet commented on ARIES-1314:
----------------------------------------
I can read the following in the osgi spec, section 121.7.11
{code}
The backing service for a reference proxy must not be gotten from the OSGi
service registry until an actual service object is needed, that is, when an
actual method is called on the proxy. If the backing service becomes
unregistered, then the proxy must unget the reference to the backing service
(if it had gotten it) and get another service object the next time a method on
the proxy is called. If a replacement can be found immediately, the reference
listener’s bind method must be called without calling the unbind method. Other
threads that need the same service object must block until the ser- vice object
has become available or times out.
{code}
I could not find anything more. Another way would be to try to modify the code
and see if the TCK passes.

> Consider the following scenario:
> Bundle X uses the service defined by API Bundle A.
> Bundle A1 implements A and has a service ranking of 1.
> Bundle A2 implements A and has a service ranking of 10.
> The bundles get started in the following order: A, A1, X, A2
> In the current implementation X will use A1 till e.g. A1 gets stopped and
> started again - according to [[email protected]] in this post:
> http://karaf.922171.n3.nabble.com/Karaf-3-0-1-does-not-consider-service-ranking-set-by-Blueprint-tp4039991p4040041.html
> I propose that X switches from A1 to A2 when A2 gets registered as A2 has a
> higher service ranking.
