---------------------------------
Resolution: Done
> Generalize module loading and initialization.
> ---------------------------------------------

> Key: JENA-2178
> URL: https://issues.apache.org/jira/browse/JENA-2178
> Project: Apache Jena
> Issue Type: Improvement
> Affects Versions: Jena 4.2.0
> Reporter: Andy Seaborne
> Assignee: Andy Seaborne
> Priority: Minor
> Fix For: Jena 4.3.0
>
>
> Jena system initialization code in {{JenaSystem.init}} provides the way extra jars can wire themselves into Jena. Initialization happens as soon as any application code touches Jena.
> The mechanism is a simple abstraction over {{java.util.ServiceLoader}}
> A new use case is to use the same machinery but for loading modules into Fuseki (example: a Apache Kafka connector for receiving updates). This loading happens after a server is built so it is happens at a different point to Jena system init.
> So separate the mechanism for module loading by interface from the specific use in {{JenaSystem}}. Use this, retaining compatibility, and allow a separate module load phase to be added to Fuseki.
