ResponseErrorHandler used in SpringAiRetryAutoConfiguration fails with Spring Framework 7.x

[ielatif]

Same issue as #3415 but for SpringAiRetryAutoConfiguration

Problem

Code breaks when users upgrade to Spring 7 because the deprecated handleError(ClientHttpResponse) method gets completely removed.

Current code:

@Override
public void handleError(@NonNull ClientHttpResponse response) throws IOException {
    // our error handling logic
}

What changed:

Spring 6.2.x: Has both handleError(response) and handleError(url, method, response)
Spring 7.x: Removes the deprecated handleError(response) method entirely

Solution

Implement both methods, but don't use @Override on the old one:

@Override
public void handleError(URI url, HttpMethod method, @NonNull ClientHttpResponse response) throws IOException {
    handleError(response);  // delegate to existing logic
}

// No @Override annotation - works in both versions
public void handleError(@NonNull ClientHttpResponse response) throws IOException {
    // existing error handling logic stays here
}

How it works:

• When using Spring 6.2.x, we call the old method directly (no overhead)
• When using Spring 7.x, we call the new method, which delegates to our logic
• Same behavior, works with both versions
