Running CaliperMain throws NPE #165

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

public class TestBenchmark extends SimpleBenchmark {
    public void timeRandom(int reps) {
        Random random = new Random();
        int count = 0;
        for (int i = 0; i < reps; i++) {
            count += random.nextInt(10);
        }
        System.out.println(count);
    }

    public static void main(String... args) {
        CaliperMain.main(TestBenchmark.class, new String[] {});
    }
}

What is the expected output? What do you see instead?

  User parameters:   {}
  Virtual machines:  [Home]
