When attempting to load a dataset formatted in JSON-LD 1.1 with the following code and data, I'm encountering the following exception with version 4.2.0

 

Data corresponding to contents of file path in Java snippet:
{quote}{{{\{ "@context": "https://linked.art/ns/v1/linked-art.json", "id": "https://www.nga.gov/collection/art-object-page.50724.html", "type": "HumanMadeObject"}}}
{quote}
and contents of the @context can be loaded from its URL.

 

Java Snippet:
{quote}InputStream in = Files.newInputStream(path);{quote}
{quote}OntModel blankModel = ModelFactory.createOntologyModel( OntModelSpec.RDFS_MEM );{quote}
{quote}RDFParser.source(in)     .forceLang(Lang.JSONLD11)     .parse(emptyModel.getGraph());{quote}
