setTimeout is not work

Hi Team
Help check option setTimeout, It is seem to me not work. I implemented on vertx 3.8.1. My brief code as below:

CircuitBreakerOptions circuitBreakerOptions = new CircuitBreakerOptions()
            .setMaxFailures(5)
            .setTimeout(100) 
            .setFallbackOnFailure(true) 
            .setResetTimeout(10_000); 
  circuit = CircuitBreaker
        .create("handler-circuit-breaker", vertx, circuitBreakerOptions);

circuit.fallback(v -> {
      // Executed when the circuit is opened
      LOG.info("fallback not work for timeout");  //code not fall this place.
      return "";
    });

    circuit.execute(promise -> {
      try {
        Thread.sleep(1000); //stay here long time more than config in option just 100ms
      } catch (InterruptedException e) {
      }
        promise.complete("OK");
    });

Thanks,
