Running generated benchmarks doesn't do anything.

I wrote the following test:

    @Test
    public void TestBenchmarkTrace() {
        int sz = 200000;
        BCBenchmarkPackage<Map<Object, Object>> pk = BCBenchmarkPackage.MAP(0, sz, 0,
                new HashMap<>());

        pk.reset();
        pk.runBenchmark(blackhole);
        blackhole.evaporate("Yes, I am Stephen Hawking, and know a thing or two about black holes.");

        BCBenchmarkPackage<Map<Object, Object>> copy = BCBenchmarkPackage.MAP("TRACE",
                pk.getTrace(),
                new HashMap<>());

        copy.reset();
        copy.runBenchmark(blackhole);
        blackhole.evaporate("Yes, I am Stephen Hawking, and know a thing or two about black holes.");

        Assert.assertEquals(sz, pk.getTrace().size());
        Assert.assertEquals(sz, copy.getTrace().size());
        Assert.assertEquals(pk.getTrace(), copy.getTrace());
        Assert.assertFalse(pk.getDataStructure().isEmpty());
        Assert.assertFalse(copy.getDataStructure().isEmpty());
        Assert.assertEquals(pk.getDataStructure(), copy.getDataStructure());
    }

The datastructure is empty, for both benchmarks, which is very unlikely.
