Re-disable Jacoco args, as they blow the build's permgen
added exception mapper handling of access control/denied exceptions
added bypass auth provider to repository.json where it was missing
removed quiet (-q) option from mvn travis command so I can investigate the build failure
Merge pull request #128 from gregjan/omit-rdf-denied-ds
