Hi Jerven,
I can only recreate this if the data has:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns>
i.e. same prefix, two settings, different URiIs
and it is TDB2 specific.
In the stacktrace:
> java.lang.IllegalStateException: Duplicate key rdf (attempted merging
> values http://www.w3.org/1999/02/22-rdf-syntax-ns# and
> http://www.w3.org/1999/02/22-rdf-syntax-ns)
the URIs are different by a #.
When run from the command line it shows as a warning and the query does
execute albeit results without prefixes.
WARN Exception in insertPrefixes: Duplicate key ex (attempted merging
values http://example/ns1# and http://example/ns2/)
Is that what you see?

Hi All,
I have a set of queries and I keep on getting this kind of stacktrace

What is the silly thing that I am doing wrong?
Explicitly binding the rdf prefix again should be ok right?
