SPARQL does not match xsd:hexBinary literals?

[Martynas Jusevičius]

Hi,

after the upgrade to 3.16.0-SNAPSHOT some queries that worked with
3.0.1 do not return results anymore.

I tried to narrow it down to a test case:

    private final String data =
"<https://localhost:4443/admin/acl/public-keys/09d7f482-6bc8-4bef-887f-6d63bc4ebc2a/#this>

    private final Model model = ModelFactory.createDefaultModel();
    private final String queryString = "PREFIX  cert:

.\n" +
"  }";

    @Test
    public void testXsdHexBinary()
    {
        RDFDataMgr.read(model, new
ByteArrayInputStream(data.getBytes(StandardCharsets.UTF_8)), null,
Lang.NTRIPLES);

        Query query = QueryFactory.create(queryString);
        try (QueryExecution qex = QueryExecutionFactory.create(query, model))
        {
            ResultSet resultSet = qex.execSelect();
            assertTrue(resultSet.hasNext());
        }
    }

The test fails as there is no result.

What baffles me is that if I save the data and the query into files
and run sparql --data=test.nt --query=test.rq, I get the expected
result:

What is the explanation here?

Thanks.
