Workaround: Include a URI "http://demo.com/";
Apache Jena uses [https://github.com/jsonld-java/jsonld-java] for JSON-LD
processing.
[https://github.com/jsonld-java/jsonld-java/pull/280]
Jena 3.16.0 uses jsonld-java 0.12.5. Upgrading to the latest jsonld-java should
include their fix.
Jena 3.16.0 was released 2020-07-09. The fix is in jsonld-java 0.13.1 which was
released 2020-09-09.

> The base URI of a jsonLD file doesn't appear to be swapped out correctly.
> The first "./" is replaced correctly with the specified base, but after that,
