Description

I'm using Jena 3.5.0 and testing the new TDB2 store. I tried to load a dataset directly into a named graph using tdb2.tdbloader.

This is my dataset:

<http://example.org/s> <http://example.org/p> <http://example.org/o> .

Loading into the default graph works:

$ tdb2.tdbloader --loc=defaultgraph example.nt 
09:16:22 INFO  TDB2                 :: Finished: 1 example.nt 0,05s (Avg: 19)

Loading into a named graph using --graph option throws an exception:

$ tdb2.tdbloader --graph=http://example.org/g --loc=namedgraph example.nt 
java.lang.ClassCastException: org.apache.jena.tdb2.store.GraphViewSwitchable cannot be cast to org.apache.jena.tdb2.store.GraphTDB
