When Nuxeo 10.10 is configured with MongoDB templates, the startup produces the following warning
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
It's due to missing classes in nuxeo-launcher-with-dependencies.jar which is copied to $NUXEO/bin/nuxeo-launcher.jar in the default distribution.
Given the fact it's only a warning, not sure it's worth backporting it.
