real osgi service which cause service tracking count to be inaccurate
Guillaume Nodet created ARIES-897:
-------------------------------------

Key: ARIES-897
URL: https://issues.apache.org/jira/browse/ARIES-897
Project: Aries
Issue Type: Bug
Reporter: Guillaume Nodet
Service tracking count is used to order the bundles when stopping those.
If the order is wrong, it can cause some bundles to go into the default 5 minutes timeout when trying to access services.

[jira] [Commented] (ARIES-897) The ReferenceRecipe lazily get the

Guillaume Nodet commented on ARIES-897:
---------------------------------------
Actually, the problem is different. The bad usage comes from the fact that the ReferenceRecipe#bind() is called twice.
Once when the manager is started, and once when the recipe is created to make sure listeners are called.
This second call cause the ungetService() method to be called and lower the usage of the service.
The service should only be unget if the new tracked ServiceReference is different from the old one.

---------------------------------------
Unfortunately, the spec says that service reference should fetch the service lazily.
