描述

Hi, I have discovered issue when using feign.httpclient.ApacheHttpClient. In some cases Apache client throws ProtocolException which is a checked exception. This happens for example when server returned 303 HTTP code but there was no location header. In such case Feign proxy throws UndeclaredThrowableException instead of invoking ErrorDecoder.

研究方向
Investigate the ApacheHttpClient class in the feign httpclient module to understand how it currently handles checked exceptions like ProtocolException. The issue likely requires modifying the exception handling to ensure that such exceptions are caught and passed to the ErrorDecoder. Look for any comments or linked PRs from the assignee for additional context. Test with a scenario where a server returns 303 without a Location header to reproduce the problem.
