The problem raised by Pavel is actually on the default logger. I haven't tested, but I think the configuration for each backend will already support OFF or NONE, depending on the provider. It just needs to be configured correctly.
For the default logger, some stuff was missing, I've committed a fix: https://github.com/ops4j/org.ops4j.pax.logging/commit/71aac7ef3f628a8923e5d1b5e6955923967b44eb Pavel, let me know if this works for you. 2017-03-31 8:52 GMT+02:00 'Achim Nierbeck' via OPS4J <[email protected] >: > In that case we have a bug that we don't forward this to the underlying > implementations. > > Someone just needs to file a bug in JIRA and we need a patch :D > > regards, Achim > > > 2017-03-31 8:16 GMT+02:00 Guillaume Nodet <[email protected]>: > >> It seems log4j, log4j2 and logback have some support for OFF. >> >> 2017-03-30 23:05 GMT+02:00 Matt Sicker <[email protected]>: >> >>> Log4j2 supports the "OFF" level which is higher than "FATAL" effectively >>> disabling logging.
