See comments in the linked issue in jena, e.g.

Not sure if CWLViewer is using Jena 4 and 3 at the same time.

Jena uses ServiceLoader to initialize so if jars from both on the classpath, then, yes, it is both (jena-core from v4, RIOT from v3). Since 3.0.1, RIOT plugged itself into jena-core as an RDFReader.

This is (not) going to be fun to tackle this issue, I think.
