Hi all, I have built a small library to target several IP behind a given HTTPS
endpoint based on java.net.http.HttpClient,
https://github.com/nhenneaux/resilient-httpclient . It relies for some
endpoints on SNI server name specified through method
java.net.http.HttpClient.Builder#sslParameters#setServerNames. Since Java 22,
it does not work properly for some endpoints, e.g. google.com. I have enabled
debug ssl logs and I get the following log indicating the SNI is ignored.
javax.net.ssl|WARNING|62|HttpClient-1-Worker-0|2024-11-18 15:51:49.496
CET|ServerNameExtension.java:265|Unable to indicate server name
javax.net.ssl|DEBUG|62|HttpClient-1-Worker-0|2024-11-18 15:51:49.496
CET|SSLExtensions.java:272|Ignore, context unavailable extension: server_name I
have a pull request showing the issue for some hosts
https://github.com/nhenneaux/resilient-httpclient/pull/68/files . Is it
something expected on Java 22+ or a bug was introduced? Thank you for your
help, Best regards, Nicolas Henneaux
