Spring Cloud Openfeign RetryableFeignBlockingLoadBalancerClient losts response content

RetryableFeignBlockingLoadBalancerClient closes stream and makes response content unavailable

When RetryableFeignBlockingLoadBalancerClient activates, closes and losts response content When is ignored, response content is available

Bug exists at least in 2.2.8.RELEASE

https://github.com/spring-cloud/spring-cloud-openfeign/blob/main/spring-cloud-openfeign-core/src/main/java/org/springframework/cloud/openfeign/loadbalancer/RetryableFeignBlockingLoadBalancerClient.java#L164

if (retryPolicy != null && retryPolicy.retryableStatusCode(responseStatus)) {
  if (LOG.isDebugEnabled()) {
    LOG.debug(String.format("Retrying on status code: %d", responseStatus));
  }

  response.close();   // that is the point

  throw new RetryableStatusCodeException(serviceId, responseStatus, response, URI.create(request.url()));
}

Affected code: https://github.com/OpenFeign/feign/blob/10.12/core/src/main/java/feign/Logger.java#L99

        byte[] bodyData = Util.toByteArray(response.body().asInputStream());  // here IOException
        bodyLength = bodyData.length;
        if (logLevel.ordinal() >= Level.FULL.ordinal() && bodyLength > 0) {
          log(configKey, "%s", decodeOrDefault(bodyData, UTF_8, "Binary data"));
        }

https://github.com/OpenFeign/feign/blob/10.12/core/src/main/java/feign/FeignException.java#L156

    byte[] body = {};
    try {
      if (response.body() != null) {
        body = Util.toByteArray(response.body().asInputStream());  // here IOException
      }
    } catch (IOException ignored) { // NOPMD
    }

Sample Without retrying, feign logs level full looks like

{"timestamp":"2021-07-01T11:25:45.782Z","status":500,"error":"Internal Server Error","message":"","path":"/foo/bar"} <--- END HTTP (141-byte body)

With retry, they looks

] <--- ERROR IOException: stream is closed (660ms) java.io.IOException: stream is closed

Additionally, response content is or is not part of FeignException, depending on retrying
