[undertow-dev] Enable HTTP/2 and get JDK9 ALPN not supported

[Steve Hu]

Hi,

I searched this mailing list and one post mentioned that I don't need to
use -Xbootclasspath/p:<path_to_alpn_boot_jar> after 1.4.0Final. I am trying
HTTP/2 on my server with 1.4.10 and Oracle JDK 1.8 but when I start the
server I got the following error. Do I have to use OpenJDK 8? If I switch
to JBoss OpenSSL implementation?

Thanks,

Steve
