> Key: FELIX-4325
> URL: https://issues.apache.org/jira/browse/FELIX-4325
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.8.0
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Fix For: scr-1.8.2
>
>
> When activating a component, the AbstractComponentManager#activateInternal
> method checks some properties, then grab the lock and actually activate the
> component, leaving a gap between the check and the lock being acquired, which
> can result in the component being deactivated in the mean time, ultimately
> leading to NPE because m_tracker has been nulled.
