Róbert Csákány commented on SLING-2151:
---------------------------------------
Thanks for answers. I understand the side effects of the version upgrade.
I've tried the other way to downgraded commons-log back to 1.5.2 of slf4j, I've
recompiled and deployed. My problem was a lot of bundle crashed with same error
as freemarker. Maybe I'm wrong, but it seems to me that bundles required 1.6.1
version be provided in commons-log - or I made a mistake.
Justin: My problemis the freemarker is not fallback to LOG4J. I don't
undersatand why when it's in Ignored-Package.
The bigger problem is when freemarker crash, all other script engines as well.
When I remove freemarker bundle everything works well.
