SSL Connection timeout with openJDK11 Client

[Robin Morris]

Hi

FYI we were getting Intermittent ssl connection timeouts using Non blocking IO java client on openJDK11.0.12.

It seems the ssl connection hangs after sending the client finish message.

java.net.http.HttpClient

HttpResponse<String> reply = client.sendAsync(request, HttpResponse.BodyHandlers.ofString()).toCompletableFuture().get();

Upgrading to openJDK17 (alpine) on the client seemed to resolve the issue.

It only seemed to be with keycloak and not other components so not sure if the server is a problem.
