[jira] Resolved: (FELIX-1414) Service ranking is only obeyed on first component activation

Felix Meschberger resolved FELIX-1414.
--------------------------------------

    Resolution: Fixed

In Rev. 799629 removed the replacement of bound services for unary references if a service was registered with a higher ranking. As per the discussion on the OSGi list, a service once bound is never replaced unless the service ceases to be a target service (by unregistration or not matching the target any more).

This resolves this issue.

>          Components: Declarative Services (SCR), Specification compliance

>             Fix For: scr-1.2.0

> As of FELIX-950 (released with scr 1.0.8) and FELIX-1213 (not released yet) unary services bindings are replaced if a new service is registered with a higher service ranking than the already bound service.
> It has been clarified in the OSGi dev list thread "Questions on DS Spec" [1] that a service once bound is only replaced if it ceaces to be a target either by the service being unregistered of the target filter not matching any longer. Service ranking is only obeyed upon first binding of a service to the component.
> To fix we have to revert the fixes for FELIX-950 and FELIX-1213.
