Description

When starting Karaf with Equinox as the OSGi Framework, you get his SLF4J warning:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/gert/opt/apache-karaf-2.0.0-fuse-SNAPSHOT/lib/karaf-client.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [bundleresource://3.fwk545215872/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

We should make sure that the class inside the client jar is no longer visible to the Pax Logging bundle to fix this.
