Spring Clarify documentation on the usage of RestClient in POST scenarios without response body

The documentation of Spring RestClient should reflect the change of behaviour in the RestClient's (or rather RestClient.RequestHeadersSpec's) retrieve() method since Spring Framework 6.2 more explicitly, especially its possible consequences in POST scenarios without response body.

The change is significant enough to break an application (which it did in my case, when I updated to Spring Boot 3.4). It took me quite some time and debugging to find out the reason although I immediately checked the above documentation.

I'm aware that the release notes for Spring Framework 6.2 and this javadoc describe the new behaviour.

But I think that an update to the above documentation would be very helpful for developers, because the current description appears to be misleading, and the new behaviour (which is: not to execute the request) is not necessarily what you would intuitively expect from a method named retrieve() and described as "Retrieve the response".

Thanks for raising this. Changes should be visible in a few minutes in the SNAPSHOT reference docs.
