Query execution fails in BSBM scenario

I have tried SparqlMap for BSBM using my own R2RML mapping. It starts without issues but the querying does not work.

The used dataset is from BSBM. Used mapping is: bsbm.txt

If I use the web interface at http://localhost:8090/ with endpoint at /api/ROOT/sparql/ (I found that it is case sensitive) the following query does not return a single result although it should return a single result (different endpoint implementation works correctly over the same dataset with the same mapping).

PREFIX bsbm-inst: <http://www4.wiwiss.fu-berlin.de/bizer/bsbm/v01/instances/>
PREFIX bsbm: <http://www4.wiwiss.fu-berlin.de/bizer/bsbm/v01/vocabulary/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?producer
WHERE {
    bsbm-inst:Product72 bsbm:producer ?p .
    ?p rdfs:label ?producer .
}

Moreover, if I try to use the BSBM runner, I am not able to run any query. I am using the following command to run it:

java -cp F:/github/bsbm/build/install/bsbm/lib/* benchmark.testdriver.TestDriver -o sparqlmap.xml -runs 1 -w 1 -ucf usecases/explore/sparql.txt http://localhost:8090/api/ROOT/sparql/

Whenever a query is executed, I get the following exception on the endpoint:

Interestingly enough, if I try the query in the browser, it executes the query (although it usually does not return anything).

If I am correct, the SparqlMap was evaluated using BSBM. Can you please provide me information how to make it working?
