-----------------------------
> Factory components are eagerly deactivated

> Key: FELIX-6315
> URL: https://issues.apache.org/jira/browse/FELIX-6315
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-2.1.20
> Reporter: Robert Varga
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Fix For: scr-2.1.24
>
>
> When a factory component with a services is is created via a call to
> ComponentFactory.newInstance(), it is treated as a delayed component where
> service reference counting is concerned. Specifically, if the resulting
> service undergoes a getService()/ungetService(), the component configuration
> is deactivated because the reference count reaches zero:

> Sorry for the non-minimal stack trace. Here OSGiDataBroker is a factory
> component, for which a configuration was created based on scanning service
> registry. As you can see, this component configuration is being deactivated
> as part of a call to BundleContext.ungetService().
> This seems to run contrary to *Figure 112.4* in R7 spec, which lists only two
> causes for deactivation:
> * when the configuration is explicitly disposed
> * when the configuration becomes unsatisified
