Jean-Baptiste Onofré commented on KARAF-6259:
---------------------------------------------
This is due of Equinox exports {{LoggerFactory}}, so Felix SCR considers it's
R7 ready, but Pax Logging is not.
I'm downgrading equinox to be back on R6 spec, and I'm upgrading Pax Logging to
OSGi R7.
> SCR feature fails to install when using Equinox framework

> Key: KARAF-6259
> URL: https://issues.apache.org/jira/browse/KARAF-6259
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.2.5
> Reporter: Amichai Rothman
> Assignee: Jean-Baptiste Onofré
> Priority: Blocker
> Fix For: 4.3.0, 4.2.6
>
>
> When starting Karaf using Equinox framework, the SCR feature fails to install
> (stack trace below). Needless to say, without SCR a whole lot of other stuff
> doesn't work, so Karaf with Equinox is basically broken.
> Steps to recreate:
> # Extract stock Karaf 4.2.5.
> # In etc/config.properties change karaf.framework=felix to
> karaf.framework=equinox.
> # Start Karaf.
> # Run 'feature:install scr' and it will fail with the exception below.
