How to skip retry in vertx circuit breaker based on condition

I am currently using Vertx CircuitBreaker to attempt retry on requesting event bus. Based on the ReplyException.ReplyFailure I want to skip or avoid retries.

For example I don't want retry when the event bus responds with ReplyFailure.RECIPIENT_FAILURE, because this kind of error are not application error instead logic validation failure.

Below is my code,

    CircuitBreaker breaker = CircuitBreaker.create("my-circuit-breaker", vertx,
                    new CircuitBreakerOptions()
                            .setMaxFailures(2) 
                            .setTimeout(5 * 1000) 
                            .setFallbackOnFailure(true) 
                            .setResetTimeout(5000) 
                            .setMaxRetries(2)
).retryPolicy(retryCount -> retryCount * 5000L);

Using circuit breaker as below,

breaker.execute(promise -> {  
            vertx.eventBus().<JsonObject>request(address, jsonObject, deliveryOptions)
                    .onComplete(event -> {

Based on the event I wan't circuit breaker to give up on retry. I tried checking event status and then called promise.complete method with the exception, though circuit breaker identifies that as failure and starts retrying. How can I tell circuit breaker to stop retrying?

I think the circuit breaker object could have

1. A method to shutdown it
2. A method to stop retry
3. A method to increment failure

Update 1 ---------------------

I have implemented the retry part on my own and for timing out the operation I can set timer and check the status of the operation, if the operation is not completed I can start retry logic. But I don't have clues on how can I cancel the operation before retrying the next one, for example how can I cancel the event bus request?

Update 2 -----------------

Vertx circuit breaker too is not handling the timed out operations. I can see older response from event bus while retry is in progress. This might confuse application logic if not handled properly.

This is not currently supported by the Vert.x Circuit Breaker API. There is an open issue about it here. There's also a PR that attempts to fix it, but it has been sitting around for a year now. Not sure why it never got reviewed.
