Felix Meschberger resolved FELIX-3506.
--------------------------------------
Resolution: Fixed
Fix Version/s: scr-1.6.2
Thanks for providing the patch.
I have applied it in Rev. 1337437 with a slight modification: The
ImmediateComponentManager.modify method only updates the service registration
after also validating service references.
> SCR bind/unbind/update methods should be able to return a map of service
> properties like the activate/deactivate/modified methods.s

> The point of this feature is to let a component respond to changes in its
> environment by changing its service properties. One of the obvious
> environment changes is for a dynamic service to be bound or unbound while the
> component is active. Therefore we should extend the "return a map" style to
> the bind/unbind/updated method.
> A simple use case I thought of.... suppose you have a service with unsecured
> functionality and secured functionality and an optional dynamic reference to
> a security service. It could use the bind and unbind methods for the
> security service to indicate in its own service properties how much
> functionality was available.
