There's a problem connecting using TLS v1.3 using JSSE (URL.openStream). Connection works on the same JDK and machine in a standalone Java program. Only when the code is executed on WildFly the server_name extension is going AWOL from ClientHello message, and the connection fails with handshake_failure. It seems to be a bug in WildFly, because it happens only when running on WildFly with the rest of the code identical.
Tested on WildFly 20.0.0.Final and 20.0.1.Final using AdoptOpenJDK 11.0.9.1_1.
