When using JdkClientHttpRequestFactory the request may block indefinitely, even if a request timeout is configured.

Details about the issue:

• https://mail.openjdk.org/pipermail/net-dev/2021-October/016672.html
• https://bugs.openjdk.org/browse/JDK-8258397

This is the problematic line, that should be updated to an async call with an immediate get on the CompletableFuture:

spring-framework/spring-web/src/main/java/org/springframework/http/client/JdkClientHttpRequest.java

Line 94 in 28e5468

this.httpClient.send(request, HttpResponse.BodyHandlers.ofInputStream());
