Why the http-client error log is only implemented for CompletableFuture responses?

[stefanos-kalantzis]

Case in point:

micronaut-core/http-client-core/src/main/java/io/micronaut/http/client/interceptor/HttpClientIntroductionAdvice.java

Line 384 in 3fc45e7

LOG.debug("Client [{}] received HTTP error response: {}", declaringType.getName(), t.getMessage(), t);
