> Key: SLING-1094
> URL: https://issues.apache.org/jira/browse/SLING-1094
> Project: Sling
> Issue Type: Improvement
> Components: Launchpad Launcher
> Affects Versions: Launchpad Base 2.0.4
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: Launchpad Base 2.0.6
>
>
> Currently the Sling launcher includes all OSGi core and compendium packages
> and exports them through the system bundle. On the other hand the OSGi
> service implementations by Apache Felix (Configuration Admin, Declarative
> Services, etc.) and oursevles (LogService) all include the actual API package
> version the implement as an export.
> Now, that Apache Felix Configuration Admin is implementing the next verison
> of the configuration admin specification (1.3) and Apache Felix Declarative
> Services trunk the next version of the declarative services specification
> (1.1) this creates issues when upgrading the respective bundles in existing
> installations:
> * The new bundles wire themselves to their own exports (because the
> version is higher than the system bundle export)
> * Running bundles are *not* rewired to the new exports
> Only when explicitily asking the respective client bundles to rewire or when
> restarting the framework will wiring to the new versions be fixed.
> This presents a real problem to running installations and is kind of
> unbearable in the spirit of OSGi.
> For this reason, the OSGi compendium export from the system bundle (by way of
> the Sling launcher) must be removed.
