Hi Jaikiran,
I still have not received your answer. Hopefully I got it from the
mailing list archive but it is not really convenient.
Are you subscribed to the net-dev mailing list? Since my replies are
reaching net-dev archives, I am guessing others who have subscribed to
net-dev list are receiving my replies (I will check with someone I know).

I am not trying to add the IP as SNI but to force the SNI value to a
specific hostname while using the IP in the URL called by HttpClient.
However, it is not working since Java 22 since the hostname from the
URL is used as SNI if valid name and none if not (like it is for IP).
I would expect the SNI provided through java.net
<http://java.net>.http.HttpClient.Builder#sslParameters#ServerName to
always be used, in addition to the hostname from the URL or only the
configured values. The first alternative is implemented in this pull
request https://github.com/openjdk/jdk/pull/22211/files.
In the following code snippet, the SNI hostname myhostname.io is not
sent during handshake while I expect it to be sent.
SSLParameters sslParameters = new SSLParameters();
sslParameters.setServerNames(List.of(new SNIHostName("myhostname.io")));
HttpClient httpClient =
HttpClient.newBuilder().sslParameters(sslParameters).build();
HttpResponse<Void> httpResponse = httpClient.send(
HttpRequest.newBuilder(URI.create("https://1.2.3.4";)).build(),
HttpResponse.BodyHandlers.discarding());
Thank you for your help,
Best regards,
