Attempting to disable TLSv1 by using

<https-listener name="https" socket-binding="https" security-realm="UndertowRealm" enabled-cipher-suites="HIGH:!aNULL:!eNULL:!PSK:!RC4:!MD5" enabled-protocols="TLSv1.1,TLSv1.2"/>

after restarting openssl s_client -connect x.x.x.x:8443 -tls1

gives me

New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-SHA

Server public key is 2048 bit

Secure Renegotiation IS supported

Compression: NONE

Expansion: NONE

SSL-Session:

    Protocol  : TLSv1

RC4 ciphers are allowed as well.

Thanks in advance!
