Freshly installed nightly build of aluminum. feature:install odl-restconf-nb-rfc8040.

There are two versions of ietf-yang-library deployed:

org.opendaylight.mdsal.binding.model.ietf:rfc7895:jar:6.0.4

org.opendaylight.mdsal.binding.model.ietf:rfc8525:jar:6.0.4

This leads to query conflict:

$ curl -u admin:admin  -X GET  http://localhost:8181/rests/yang-library-version

{"ietf-restconf:yang-library-version":"2016-06-21"} 

$ curl -u admin:admin  -X GET  http://localhost:8181/rests/data/ietf-yang-library:modules-state?content=nonconfig

{"errors":{"error":[{"error-tag":"data-missing","error-type":"protocol","error-message":"Request could not be completed because the relevant data model content does not exist"}]}}

However if all data is requested, it finally returns ietf-yang-library:modules-state:
