The Jackson version aligned across most of Fuse 6.3 is 2.6.3. However, for fabric8 we currently build using Jackson 2.7.4.

Quickstart karaf2-camel-rest-sql declares dependencies on features kubernetes-karaf & fabric8-karaf-features. If you run the build and examine the karaf assembly, you'll see that the Jackson library versions are all 2.7.4, which differs to what the Fuse camel 2.17 camel-jackson would usually expect (2.6.3).

Not sure if this a big problem or not.
