Fixes #6413
When retry is enabled, exchange.getRequest().getBody() (a single-use FluxReceive) is exhausted after the first attempt. Retry subscriptions emit onComplete immediately, so upstreams receive an empty body — silent data loss with no error logged.
Add getCachedRequestBody(): DataBufferUtils.join → read byte[] → .cache() → Flux.defer(wrap) per subscription.
Make sure that:
