A. Soroka commented on JENA-1139:
---------------------------------
Well, as someone from a project (Fedora Commons) that relies on Jena working in
OSGi, I'd like to see it work as well as possible. *grin* More usefully,
{{jena-osgi}} is not a good way to track usage. OSGi frameworks and containers
like Apache Karaf offer "wrapping" techniques for autosupplying the needful
OSGi metadata to unequipped JARs. It's not possible to say how many downloads
of ordinary Jena JARs are getting used in OSGi systems.

> Key: JENA-1139
> URL: https://issues.apache.org/jira/browse/JENA-1139
> Project: Apache Jena
> Issue Type: Bug
> Components: OSGi
> Affects Versions: Jena 3.0.1
> Reporter: Stian Soiland-Reyes
> Assignee: Andy Seaborne
> Fix For: Jena 3.1.0

> As discovered in TAVERNA-892 the jena-osgi of Jena 3.0.1
> seems to have not merged correctly
> META-INF/services/org.apache.jena.system.JenaSubsystemLifecycle
> which breaks the new Jena initialization - only TDB is initialized - but TDB
> depends on ARQ already being initialized (to get its context).
> {code}
> stain@biggie:~/.m2/repository/org/apache/jena/jena-osgi$ unzip
> ./3.0.1/jena-osgi-3.0.1.jar
> META-INF/services/org.apache.jena.system.JenaSubsystemLifecycle
> Archive: ./3.0.1/jena-osgi-3.0.1.jar
> inflating: META-INF/services/org.apache.jena.system.JenaSubsystemLifecycle
> stain@biggie:~/.m2/repository/org/apache/jena/jena-osgi$ cat
> META-INF/services/org.apache.jena.system.JenaSubsystemLifecycle
> org.apache.jena.tdb.sys.InitTDB
> {code}
> So basically only the last JenaSubsystemLifecycle file survives when shading
> jena-core, jena-arq, jena-tdb, jena-iri with Embed-Dependency and inline=true.
> The equivalent of the Maven Shade plugin's ServicesResourceTransformer would
> be able to merge these.
> https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#ServicesResourceTransformer
> but I'm not sure how this can be done with the bundle plugin. I guess it
> could be overridden with its own src/main/resources/META-INF/services/ file
> in jena-osgi as well - but then it needs maintenance.
