Subject [jira] [Commented] (SLING-7234) ServiceFactory.getService() resulted in a cycle in sling karaf
Date Fri, 08 Dec 2017 19:51:00 GMT


Oliver Lietz commented on SLING-7234:

Scripting Core > 2.0.48 is broken and fails on Karaf (update Scripting Core in Sling's
Karaf Features and Launchpad Oak Tar ITs will fail immediately).
I hadn't time to dig into it yet, but will probably next week. [~radu.cotescu], [~karlpauls]
you both did some major changes recently – any ideas?

> Hello,
> Once in a while on the first startup of Sling on Karaf I'm seeing the exception ServiceFactory.getService()
resulted in a cycle. This does not happen every time only on some startups. 
> After the first startup on the next restart this exception does not appear anymore.
> I've picked a sample of the exception. Unfortunately this seems like a concurrency issue
and therefore much harder to find a pattern but it happens mostly with sling scripting. I've
seen other exceptions also with sling scripting but this one is the most common 
> I've uploaded two log files:
> clean.log.1 with a clean startup and
> sample.log.1 with the aforementioned exception
