Bertrand Delacretaz commented on SLING-3185:
--------------------------------------------
What happens at startup of my patched launchpad is
{code}
[Loaded org.slf4j.helpers.SubstituteLoggerFactory from
slinginstall:slf4j-api-1.6.4.jar]
[Loaded ch.qos.logback.classic.LoggerContext from
slinginstall:org.apache.sling.commons.log-3.0.3-SNAPSHOT.jar]
*ERROR* [FelixStartLevel] ERROR: Error starting
slinginstall:org.apache.sling.commons.log-3.0.3-SNAPSHOT.jar
(java.lang.ClassCastException: org.slf4j.helpers.SubstituteLoggerFactory cannot
be cast to ch.qos.logback.classic.LoggerContext)
at
org.apache.sling.commons.log.logback.internal.LogbackManager.<init>(LogbackManager.java:101)
at
org.apache.sling.commons.log.logback.internal.Activator.start(Activator.java:55)
{code}
According to Chetan, logback uses its own classloader, that's probably what
causes the ClassCastException.
Once Sling starts, the commons.log bundle starts without problems.
> Circular dependency between o.a.s.commons.log and slf4j.api

> Key: SLING-3185
> URL: https://issues.apache.org/jira/browse/SLING-3185
> Project: Sling
> Issue Type: Bug
> Components: Commons
> Affects Versions: Commons Log 3.0.0
> Reporter: Bertrand Delacretaz
> Priority: Minor
>
> with the initial launchpad runmodes patch of SLING-3155, the
> org.apache.sling.commons.log bundle does not start initially, due to a
> circular dependency:
> commons log imports org.slf4j,version=1.6.4 from slf4j.api
> slf4j.api imports org.slf4j.impl,version=1.6.4 from
> org.apache.sling.commons.log
