RDF-star is still under development. In fact I just looked at the W3C mailing 
list of the WG that is supposed to standardize RDF-star. At this stage I find 
it too early to commit to something that may evolve further. It wouldn't be the 
first time that a WG comes up with some weird compromise solution that makes 
nobody happy in the end. We have solved the practical use cases with our 
URI-based reification approach and many customers are using it to get work 
done. That's good enough for me. There would be significant investment cost for 
us if we want to support the implementation from Jena because it introduces a 
completely new node type that would need to be handled, gracefully, in all of 
our algorithms.

You can see the actual triples when you export to vanilla Turtle, if you're 
interested in the implementation details.
