Pierre De Rop resolved FELIX-5242.
----------------------------------
Resolution: Fixed
Committed a patch in rv 1741103.
To avoid the race conditions, the updated method is scheduled in the component
executor queue, but of course, the completion of the method is awaited from the
CM thread, in case the component "updated" callback has thrown a configuration
exception.
> Configuration updates may be missed when the component is restarting

> Key: FELIX-5242
> URL: https://issues.apache.org/jira/browse/FELIX-5242
> Project: Felix
> Issue Type: Bug
> Components: Dependency Manager
> Affects Versions: org.apache.felix.dependencymanager-r1
> Reporter: Pierre De Rop
> Assignee: Pierre De Rop
> Fix For: org.apache.felix.dependencymanager-r9
>
>
> When a component has some required dependencies, and also has a configuration
> dependency, then some configuration updates may be missed in the following
> situation:
> 1) the component has lost a required dependency: it is stopped.
> 2) the component is restarting because the lost required dependency becomes
> available again.
> 3) at the same time, concurrently, a configuration update is taking place.
> Then, during this racy condition, it is possible (but not systematically)
> that the component misses the configuration update.
> I have a test which demontrates this issue, as well as a patch. I will commit
> it soon.
