Unable to install KAR containing camel-spring: spring beans missing - spring

Question

I've built an application bundled in an OSGi JAR package and now I'm trying to create a KAR file to easy deployment to Apache Karaf 4.0.8.
When I drop the KAR file there's a warning message complaining that it's impossible to resolve camel-spring due to the missing org.springframework.beans requirement.

I cannot figure why this is happening! The kar file does contain spring-beans JAR file of an appropriate version:
$ unzip -l interfacturas-kar-1.0.0-SNAPSHOT.kar
...
614354 2017-01-11 19:07 repository/org/springframework/spring-beans/3.2.16.RELEASE/spring-beans-3.2.16.RELEASE.jar
...
The KAR file and its associated feature XML file is completely generated by karaf-maven-plugin, and it also lists the spring-beans dependency:
<bundle>wrap:mvn:org.springframework/spring-beans/3.2.16.RELEASE</bundle>
along with other spring related resources.
Any has some idea how to fix this? Or why is it happening?
BTW, camel-spring actually comes as a dependency of camel-cxf; I'm using blueprint for defining the routes.
