> Make Camel OSGI Extender Subsystem-Aware
> ----------------------------------------
>
> Key: CAMEL-8647
> URL: https://issues.apache.org/jira/browse/CAMEL-8647
> Project: Camel
> Issue Type: Improvement
> Components: camel-core, osgi
> Reporter: Manuel Holzleitner
> Assignee: Christian Schneider
> Fix For: 2.16.0
>
>
> I would like to propose a change to the camel-core extender for components,
> type converters, etc. to allow to use camel-core with subsystem-aware
> OSGI-containers to separate components and it’s dependencies into subsystems.
> This would allow to isolate applications and camel components (incl. it’s
> libraries) from each other. I.e. you could run HTTP-related components that
> rely on (otherwise conflicting) HTTP client libs in different versions next
> to each other.
> Currently, the BundleTracker in the camel-core extender is initialized on its
> own BundleContext and therefore does not receive any events from started
> camel component bundles that reside in subsystems. I discussed a solution to
> make the camel extender subsystem-aware in the Aries mailinglist [1], who
> already conducted this change in the blueprint implementation.
> This approach from the upcoming R6 DS 1.3 spec was proposed by David Jencks
> as a solution:
> - use the system bundle (bundle 0) to look for events of interest, so you
> see them for all bundles
> - have the extender register an extender capability
> - have bundles that need extension register a matching extender requirement
> - the extender should only extend bundles with no extender requirement or
> ones with extender requirements wired to their own extender capability.
> I implemented this approach accordingly for camel and tested it in
> combination with the Aries subsystem module. Any feedback to this would be
> very much appreciated.
