Its the OSGi problem that it often cannot use maven jars out of the
box. So SpringSource creates their own .jar that works in their OSGi
server.
IMHO that is a big pain with OSGi as you need to keep up to date with relea=
ses.

Many projects don't release their .jars as OSGi compliant bundles.

It should be possible to use a never version and then let the camel
feature for camel-cache use that Spring OSGi compliant .jar.
Just that they are API compatible.

Can you pin point the problem.
