Carsten Ziegeler commented on FELIX-5507:
-----------------------------------------
Well you assume that you have a shared config admin API across the whole system
- which is a false assumption and can't be guaranteed at all. It's really wrong
to assume that the config admin class you get using the extended bundle is the
same as SCR sees. It might not be that common, but it's still possible.
As I've mentioned earlier on, we should at least catch the class cast exception
and provide a meaningful log entry. Atm I'm not very keen on using reflection
all over the place either

> Key: FELIX-5507
> URL: https://issues.apache.org/jira/browse/FELIX-5507
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-2.0.8
> Reporter: Carsten Ziegeler
> Assignee: Carsten Ziegeler
> Fix For: scr-2.1.0
>
>
> We have one case where the extended bundles do not see the configuration
> admin service. Interestingly the same application runs fine everywhere else,
> but just on a special environment (windows, ibm java inside Websphere) we
> have this problem reproducibly.
> Using the system bundle context instead of the bundle context of the extended
> bundle in ConfigAdminTracker solves the problem.
> Interestingly only the bundles started last (2 out of probably 80) see the
> configuration admin.
> It could also be that a faulty service hook is involved, although I'm not yet
> aware of such a hook
> Update: after some discussion, some issues in the framework have been
> identified, but also the SCR implementation is not 100% correct: as it is
> using the bundle context of the extended bundle, it might get a configuration
> admin which interface is not visible to SCR. Therefore it should revert to
> reflection to access the configuration admin.
