Reactor Retry: reactor.retry.Retry vs. reactor.util.retry.Retry

Question

First time I use retry pattern in reactor.

I have got totally confused with the management of retrying in reactor. The main source of confusion is the existing 2 Retry classes in the same package!

I want to retry a Mono/Flux process when specific exceptions happens, during a max number of times.

My first step is create a reactor.retry.Retry in this way.

reactor.retry.Retry retry = reactor.retry.Retry
        .anyOf(
                WebClientResponseException.BadRequest.class,
                WebClientResponseException.BadGateway.class)
        .retryMax(nRetries);

And then, I want to parameterize my mono with

mymono.retryWhen(utilRetry);

Following the documentation in Interface Retry I have to convert the reactor.retry.Retry object in a reactor.util.retry.Retry using the method withThrowable, but there is no sample (and the sample in the doc doesn't work because the objects are not compatible).

So, I'm looking for something like

utilRetry=retry.somemethod()

Any comment for newbie will be welcome!

UPDATE:

I have found this issue reactor.retry.Retry does not provide methods for Mono.retryWhen(Retry retrySpec) #231 where it seems there is some migration conflics, but does not provide a canonical solution
