{code}

{"@context": "https://w3id.org/bundle/context";,
"id": "http://example.com/fred";,

> <httpcore.version>4.4.4</httpcore.version>
> {code}
> while we explicitly depend on a much older version:

> <!-- These are connected because solr4j depends on httpclient as well -->
> <ver.httpclient>4.2.6</ver.httpclient>
> <ver.httpcore>4.2.5</ver.httpcore>
> {code}
> Issue JENA-576 discusses why HTTPClient was not upgraded.
> I suggest we try again to upgrade HTTPClient, even if this means also a newer
> Solr.
> A workaround would be to have an initialization to set
> JsonUtils.setDefaultClient() with our own instance - however that would break
> JSON-LD [Context JAR
> caching|https://github.com/jsonld-java/jsonld-java#loading-contexts-from-classpathjar]
> which I know we use in Taverna to avoid network traffic.
> As JSON-LD with external @context - e.g. with schema.org, is the primary way
> to use JSON-LD, then I think this should be a blocker for 3.1.0
