Oliver Lietz commented on SLING-5401:
-------------------------------------
[~bdelacretaz], you're right. The import is optional and the bundle is in state
{{active}}.

There are several things getting in my way with testing against Karaf, but as I
was close to 100% success and Sling is running fine in production on Karaf I'm
close to removing
{{org.apache.sling.launchpad.karaf-launchpad-oak-tar-integration-tests}}
finally. It's maybe not worth the effort to maintain that module.
> JUnit Core has hard dependency on Logback
> -----------------------------------------
>
> Key: SLING-5401
> URL: https://issues.apache.org/jira/browse/SLING-5401
> Project: Sling
> Issue Type: Bug
> Components: Testing
> Affects Versions: JUnit Core 1.0.12, JUnit Core 1.0.14
> Reporter: Oliver Lietz
>
> While investigating why [running launchpad integration tests against Sling on
> Karaf|SLING-3821] suddenly completely fail I found that JUnit Core has now a
> hard dependency on Logback because of {{TestLogServlet}}.
> That means if your system under test does not use Logback as backend testing
> is not possible at all. That should be documented at least at [JUnit
> server-side testing support
> bundles|https://sling.apache.org/documentation/bundles/org-apache-sling-junit-bundles.html].
> [~chetanm], [~bdelacretaz]: Is that hard dependency really desired?
