Description
I was trying to be a good person and implement the Mozilla "Modern" cipher suite described here:
https://wiki.mozilla.org/Security/Server_Side_TLS
I'm doing this in a keycloak server. The config line there looks like
<https-listener security-realm="ApplicationRealm"
enabled-protocols="SSLv2Hello,TLSv1.2"
enabled-cipher-suites="TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384:TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384:TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256:TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256:TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256:TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256:TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384:TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384:TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256:TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256"
name="default"
socket-binding="httpish"
enable-http2="true"
proxy-address-forwarding="true"
/>
But I got this:
13:20:46,574 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service org.wildfly.undertow.listener.default: org.jboss.msc.service.StartException in serv

With a little digging it appears that CipherSuiteSelector doesn't know what CHACHA20 or POLY1305 are. See:
