> To make long story short, it seems that in the process of building jar, someone forgot to move META-INF/services files in separate bundles.
> In OSGI enviroment, classpath loader of one bundle can only see files in jars (bundles) which he has import directive, including local root. In current build of activemq, META-INF/services files are all stored in META-INF/services dir under activemq-core bundle.On the other hand, namespace parser is in xbean.spring bundle (referenced by META-INF/spring.handlers). Because parser is in separate bundle, it can not "see" META-INF/services directory, and it dies. Also, import for org.apache.xbean.spring.context.v2 is missing from activemq-core. Additionally, for bundle loader to scan for spring.schema file, bundle _must_ import org.springframework.beans.factory.xml, which is also missing from manifest file. I'm not 100% shure in this, maybe all files from META-INF/services should be moved from activemq-core to xbaen.spring ...
> Anyhow, fix to make it work is to:
> - move META-INF/services in propriate bundles
> - add following import to activemq-core:
> org.springframework.beans.factory.xml;resolution:=optional,
> org.apache.xbean.spring.context.v2;resolution:=optional
> That's it for now. :-)
