Problem

Our code breaks when users upgrade to Spring 7 because we override the deprecated handleError(ClientHttpResponse) method that 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
