> With scr from trunk: sometimes, a satisfied Reference bind method is not invoked.
> I'm not sure, but this might be related to the FELIX-3659 issue and/or when Reference
types are org.osgi.service.ComponentFactory types.
> The use case is the following:
> - I have a DS component (name="agent"), which depends on the CompositeFactory service
(ref is dynamic, optional, cardinality=0..N).
> - the "agent" component is started (at this point), the CompositeFactory is not yet available
> - next, the implementation bundle for the CompositeFactory service starts and registers
the service, using bundleContext.registerService.
> - but the "agent" component is not invoked in its bindCompositeFactory(CompositeFactory)
method.
> I have attached a logfile which illustrates the problem.
> 1) Line 8491: the '"agent" component is being created, and some bind method are successfully
invoked, except the "bindCompositeFactory" method (but this is normal since the service is
optional, and not yet available):

> (here the bind for loggerRepository is invoked, but not for compositeFactory ... normal
behavior for now.
> 2) at line 8644, the CompositeFactory service is being registered, but we see the "component
not yet created, assuming bind method call succeeded" log and the bindCompositeFactory method
on the "agent" component is not invoked. 
> However, another "com.alcatel_lucent.as.service.composite.impl.shell.FelixCompositeCommand"
DS component is succesfully bound with the CompositeFactory, but this component depends on
the CompositeService, using a ServiceReference type, instead of the actual CompositeFactory
type, in the bind method signature ...
