Andy Seaborne commented on JENA-1423:
-------------------------------------
TDB2 is stamping on the {{tdb:}} registration and making it
{{http://jena.apache.org/tdb#}}.
Workaround: use the full name: {{--set
http://jena.hpl.hp.com/TDB#unionDefaultGraph=true}}.
The ideal solution is that "tdb:" works naturally for both TDB1 and TDB2
without solely being set to {{jena.hpl.hp.com}}.

> {noformat}
> I've loaded this into a TDB1 using
> {noformat}
> tdbloader --loc tdb graphs.nq
> {noformat}
> This is my query:
> {noformat}
> SELECT * { ?s ?p ?o }
> {noformat}
