Aaron Whiteside commented on CAMEL-4537:
----------------------------------------
Spring DM 2.0 support is essential, because of the classloading issues with
Spring DM 1.x.
I understand Spring DM 2.0 is not yet final, but it's a hell of a lot better
than Spring DM 1.x. and no we cannot currently use Blueprint.
> Support for Spring DM 2.0
> -------------------------
>
> Key: CAMEL-4537
> URL: https://issues.apache.org/jira/browse/CAMEL-4537
> Project: Camel
> Issue Type: Bug
> Components: osgi
> Affects Versions: 2.9.0
> Environment: JBoss 7.0.2 - OSGi
> Reporter: Aaron Whiteside
> Priority: Critical
> Labels: OSGi, Spring
>
> The camel-spring-2.9-SNAPSHOT.jar bundle imports
> org.springframework.osgi.context;version="[1.2,2)";resolution:=optional,
> Which obviously excludes Spring DM 2.0.0M1
> I am not sure if Spring DM 2.0 breaks anything Camel is trying to use, but
> the class org.springframework.osgi.context.BundleContextAware it is searching
> for on startup does exist in spring-osgi-core-2.0.0.M1.jar.
> Currently when I deploy Camel 2.9-SNAPSHOT in JBoss 7.0.2 with Spring DM
> 2.0.0M1 I get the following error, and I am unable to resolve any Components
> from the OSGi Service registry - obviously because Camel is not trying to use
> it.
