> Key: FELIX-5429
> URL: https://issues.apache.org/jira/browse/FELIX-5429
> Project: Felix
> Issue Type: Bug
> Components: Dependency Manager
> Affects Versions: org.apache.felix.dependencymanager-r1
> Reporter: Pierre De Rop
> Assignee: Pierre De Rop
> Priority: Minor
> Fix For: org.apache.felix.dependencymanager-r9
>
>
> This issue concerns the following corner case scenario:
> You have a component A with a required dependency on "Required" service, and
> an optional dependency on a "B" service.
> You have also an aspect for the "B" service.
> So, when A starts, it will be called in
> - A.add(Required)
> - A.add(originalBService)
> - A.swap(originalBService, aspectForBService) // assuming the aspect is
> started after B service and after A
> Now, there is a a ComponentStateListener on A which removes the B aspect when
> the "A" component is stopping.
> So, the bug is the following: when you remove the "Required" Service, A is
> called in :
> - A.remove(originalBService)
> - A.stop()
> so, here the A component should have been called like this
> - A.swap(aspectForBService, originalBService)
> - A.remove(originalB)
> - A.stop()
> Here, the swap callback should be called because the state listening is
> removing the aspect while A is stopping.
