I am reading a file using the following:

Wrong API call. The two arg version takes the base URI, not the language.
Model.read(InputStream, baseURI)
Try:
myModel.read(myInputStream, null, "JSON-LD");
or (better type checking):
RDFDataMgr.read(model, myInputStream, Lang.JSONLD);
or (buildler style arguments - this is what RDFDataMgr is built on):
RDFParser.source(myInputStream).lang(Lang.JSONLD).parse(model);

I get an exception:
org.apache.jena.riot.RiotException: [line: 1, col: 1 ] Content is not
allowed in prolog.

The "ReaderRIOTRDFXML" makes me wonder if Jena is trying to input my
data in RDF/XML rather than JSON-LD format.
Correct.
I am still on Jena 3.17. Do
I need a later version to read JSON-LD?
No.
