Subject [jira] [Commented] (FELIX-5507) ConfigurationAdmin might not be visible to SCR implementation
Date Thu, 16 Feb 2017 06:18:41 GMT

    [ https://issues.apache.org/jira/browse/FELIX-5507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15869311#comment-15869311

Carsten Ziegeler commented on FELIX-5507:

You are subscribing a solution because you don't want to handle it in the implementation.
And this is really not infinite complexity - as Karl said, it's a simple check: do I need
to proxy, if no, fine, if yes, create the proxy and done
Why can't I have a config admin including API in a subsystem and a global DS? We nowhere say
something about how you should do it. Users are free to shoot themselves in the foot in any
way they like

>             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
> 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.
