Sending "supported_groups" in ServerHello does not comply to the
extension specification. Is it possible the HTTPS server fix this problem?
I filed a bug in OpenJDK for the tracking:
https://bugs.openjdk.java.net/browse/JDK-8209965
Thanks,

As noted in that exception message, it appears that the server is
sending a "supported_groups" extension in its ServerHello message
(TLSv1.2). Reading about it, this seems to be a common issue with
certain servers and certain SSL implementations have added support to be
lenient with such servers https://github.com/openssl/openssl/pull/4463/files

While testing the recently released RC of JDK11 against the Apache Ant
project, I happened to run into an odd error. I have now been able to
reproduce this using the following, pretty trivial code:
import java.net.URL;
import java.io.InputStream;
public class Fetch {
public static void main(final String[] args) throws Exception {
final URL targetURL = new
URL("https://repository.jboss.org/nexus/content/groups/public/javax/media/jai-core/1.1.3/jai-core-1.1.3.pom";);
try (final InputStream is =
targetURL.openConnection().getInputStream()) {
is.read();
}
System.out.println("Done");
}
}
All it does is opens a (HTTPS) connection against an endpoint to read
some content. This code works fine in Java 8 and even Java 10. I'm
pretty sure this was working fine even in Java 11 early access builds,
but I don't have any such build/binary at hand to be certain.
However, using the latest (OpenJDK) RC of Java 11 (both on Mac OS and
Linux) downloaded from[1]:
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment 18.9 (build 11+28)
OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)
it fails with:
