You can look up dependency versions in the top level pom.xml Specifically for JSON-LD - https://github.com/apache/jena/blob/master/pom.xml#L59-L63 - we are currently at 0.12.1
As noted on the JSON-LD libraries repository - https://github.com/jsonld-java/jsonld-java - they implement the JSON-LD 1.0 and the spec you reference is 1.1 so if the feature you are trying to use is only present in the 1.1 spec it won't be supported.
