QPID-5762: log a warning but allow the model processing to continue when there
are unsatisfied dependencies, enabling startup if the associated pluggable
services are not being used
> Broker won't start from default broker artefact unless JE is added to ./lib

> Key: QPID-5762
> URL: https://issues.apache.org/jira/browse/QPID-5762
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.29
> Reporter: Keith Wall
>
> If I build the Java Broker from Maven, then try and start the Broker from the
> artefact at broker/target/qpid-broker-0.30-SNAPSHOT-bin.tar.gz, I find the
> Broker fails to start with the following exception:
> {noformat}
> Exception during startup: java.lang.NoClassDefFoundError:

> {noformat}
> The problem is that the Broker now introspects the whole model on startup,
> this discovery process encounters the classes within qpid-bdbstore-*.jar,
> which then fails owing to the fact that the (BDB) je.jar cannot be found. JE
> itself is intentional optional owing to license constraints.
> We either need to make the COTR tolerant to such exceptions (perhaps logging
> a message) and/or change the packaging so that qpid-bdbstore-*.jar is
> excluded from the default artefact.
