It seems that FUSE 4.3.0 (both 00-00 and 01-00) has duplicates for 'spring' and 'spring-dm' features located in:
While they are quite similar they have differences:
Spring: spring feature from "apache-camel/2.4.0-fuse-00-00" is bigger. It have every bundles plus spring-aspects.
Spring-dm: spring-dm feature from "apache-karaf/2.0.0" is bigger. It has bundle org.apache.karaf.deployer.spring/2.0.0 that is missing in feature from "apache-camel/2.4.0-fuse-00-00".
Thanks for reporting this -- I've raised http://fusesource.com/issues/browse/ESB-1275 for this. We're preparing for 4.3.0-fuse-02-00 at the moment, so we might just be able to get this in in time for that.
