Spring version bound to Camel

[Cristiano Costantini <cr...@gmail.com>]

Hi all,

I'm updating from using Camel 2.13.2 to Camel 2.16.1.
I want to keep the spring version we use in sync to the version used in
camel (specifically "camel-spring").
Do you suggest me to keep using Spring 3.2.x or should I upgrade to Spring
4.1 as a follow up of upgrading from Camel 2.13.2 to Camel 2.16.1?

My concerns arrise from the following facts...

The camel-spring artifact is using "Spring 4.1.9.RELEASE":

But the camel-spring feature for karaf seems to be bound to "Spring 3.2.x":

karaf@root>feature:info camel-spring
Feature camel-spring 2.16.1
Feature has no configuration
Feature has no configuration files
Feature depends on:
spring [3.2,4)
spring-dm [1.2,2)
spring-tx [3.2,4)
camel-core 2.16.1
Feature contains followed bundles:
mvn:org.apache.geronimo.specs/geronimo-jta_1.1_spec/1.1.1
mvn:org.apache.camel/camel-spring/2.16.1
Feature has no conditionals.


Shouldn't the camel-spring feature use or at least support spring 4?
=> spring [3.2,5)

Thank - again - you for the help and feedback!
