The following warning is displayed whenever we run the FDP or tests:

Standard Commons Logging discovery in action with spring-jcl:
please remove commons-logging.jar from classpath in order to avoid potential conflicts

Probably best to follow this advice, or at least investigate the cause.

It is likely we'll need to exclude commons-logging in the pom.xml similar to this:

spring-projects/spring-data-elasticsearch#1989

Looks like commons logging is pulled in by rdf-resource-resolver-core via httpclient.
