----------------------------------

             Summary: NPE with wildfly-openssl using OpenSSL 1.1.1a
                 Key: WFLY-11650
                 URL: https://issues.jboss.org/browse/WFLY-11650
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 15.0.1.Final
         Environment: OpenSSL 1.1.1a
            Reporter: Jan Stourac
            Assignee: Stuart Douglas


It is impossible to use {{wildfly-openssl}} binding with OpenSSL 1.1.1a (RHEL8 uses 1.1.1 at the moment but there seems to be same issue). There is an NPE during the ciphersuites initialization:
{code}

and then there is NPE during the request itself:

{code}

Looking briefly into it, the cipher that is trying to be used is *{{TLS_AES_256_GCM_SHA384}}*. It is interesting that this cipher has underscores '_' in its name instead of hyphens '-' as most of the openssl ciphers have. Looks like these were added in the sake of TLSv1.3, [see here|https://github.com/openssl/openssl/commit/fa25763b5528b56b448d64bfbaeac54905b0c80d].
