Jean-Baptiste Onofré commented on KARAF-1312:
---------------------------------------------
The org.ops4j.pax.logging configuration contains log4j properties.
The problem is that it's possible (during sync) to have, during a short time,
two properties in ConfigAdmin, which mean two times the same appender, which
raise the error.
A "simple" workaround is to blacklist org.ops4j.pax.logging.
However, due to the latest change on config layer, it should be better now.
