Droolsjbpm has several components that depend on camel 2.10.3, all in this repository:
  https://github.com/droolsjbpm/droolsjbpm-integration
Such as
- kie-camel
- drools-camel-legacy5
- drools-osgi/drools-karaf-features (IIRC)
- drools-osgi/drools-karaf-itest (IIRC)

If this were an upgrade, we'd accept it, even if it would cause us trouble.
However, since its a downgrade
and IIRC camel version changes is always trouble (especially in the unit tests),
we are currently not-acking this change.

@etirelli Can you assign someone too look into this issue?
