This has made the tolerance even less: < start+200 is stricter than < start+500. I'd write something like:

    long start = System.currentTimeMillis();
    LanguageUtils.repeatUntilSuccess(period: 1*TimeUnit.MILLISECONDS, timeout: 5000*TimeUnit.MILLISECONDS) { 
        System.currentTimeMillis() > start+50 
    }
    long time = System.currentTimeMillis() - start;
    assertTrue(time >= 50, "time="+time);
    assertTrue(time <= 1000, "time="+time);

Will see if buildhive thinks this is good enough to fix the test failure, and then merge.

The test passed in buildhive, but then failed at:

CliTest.testLaunchCommandParsesArgs:188 LaunchCommand{verbose=false, quiet=false, app=my.App, script=null, location=localhost, port=8081+, noConsole=false, noShutdownOnExit=false, stopOnKeyPress=false} expected [true] but found [false]

So merging.
