Heya, I've been testing the Http3 support on windows 11 with build 26-ea+22-2263, and my request was seemingly just timing out.
After like 3 hours of fiddling, I realized that I forgot to import the mkcert rootCA I was using into the jdk cacerts. Long story short, when I ran `keytool -import -trustcacerts -noprompt -alias mkcert-root-ca -file "$(mkcert -CAROOT)/rootCA.pem" -keystore "$JAVA_HOME/lib/security/cacerts" -storepass changeit` then it suddenly began to work. Perchance is it possible to get a clearer error message? Feedback wise, I like the new feature, that using it only involves providing the new enum value is great for me so I don't have to do much to my internal libraries to make it work. On an unrelated note, what do we think about adding a HttpServer Create Convenience Method <https://mail.openjdk.org/pipermail/net-dev/2025-October/028587.html>? -- Cheers, Josiah.`
