private static String generateStatusJson() {
    Builder builder = new Builder();

    Status status = Status.ONLINE;
    LocatorState locatorState = new LocatorState(defaultLauncher, status);
    return locatorState.toJson();

This is a new test written for GEODE-3413: "Overhaul launcher tests and process tests."
Unfortunately, it hangs so I have filed GEODE-3278. This test should be used to fix and verify
that bug.
