complete. The JVM exits.

I am getting the same problem.

#1, windows also?  I don't have a windows machine, but I'll see if I can 
reproduce on another OS.

Yea, I am running windows and also ran into a similar problem with a build from 
today (11/05/2013).

I also tried with an extremely simple class and same result:

    public boolean runTests() {
        return true;
    }

    @Benchmark 
    public int time(int reps) {
        System.out.println("Starting "+reps+" tests.");
        boolean passed = false;
        for (int i = 0; i < reps; i++) {
            System.out.println("hi");
            try {
                passed = runTests();
            } catch (NullPointerException e) {
                System.err.println(string);
                throw e;
            }
            if (!passed) break;
        }
        if (passed) System.out.println("Tests finished. All passed.");
        else System.err.println("Tests finished. Detected a failure.");
        return -1;
    }

    public static void main(String[] args) {
        com.google.caliper.runner.CaliperMain.main(DataStructuresMicrobenchmark.class, args);
    }

Mind including output with --verbose?

Original comment by gak@google.com on 5 Nov 2013 at 9:34

[GoogleCodeExporter]

It doesn't seem to make a difference if I include verbose or not. I used the 
following in my main and it produced the same output.

CaliperMain.main(DataStructuresMicrobenchmark.class, new String[]{"--verbose"});

Actually, I think I found "a" problem... 

default config was:
vm.args=-Xmx3g -Xms3g

Which is too large, I narrowed it down to:
vm.args=-Xmx1g -Xms1g

It actually executes now...

Original comment by phishman3579@gmail.com on 5 Nov 2013 at 9:44

[GoogleCodeExporter]

That's surprising.  Can you run
$ java -Xmx3g -Xms3g -version
and see if it crashes?

Original comment by gak@google.com on 5 Nov 2013 at 9:49

[GoogleCodeExporter]

Works fine from the command line, maybe it because the benchmark is being run 
from inside an IDE?

java -Xmx3g -Xms3g -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

I'm running it from within IDE (IntelliJ 12.1.6)

It fails for me on OSX Mountain Lion x64
