https://github.com/eclipse/rdf4j/issues/1405
Several tests in HalyardComplexSPARQLQueryTest have to be skipped due to the issue.

Research direction
Start with HalyardComplexSPARQLQueryTest and identify the tests skipped because variables from outside a group are visible inside it. Read the linked RDF4J issue for the expected scoping behavior, then trace the relevant SPARQL query evaluation entry points. Done means the scoping behavior is corrected and the skipped tests pass without being skipped.
