Description
Preface
mod_cluster subsystem doesn't use Security Realms, unfortunately, so one must replicate SSL configuration both in security realms and in mod_cluster subsystem.
Apparently, there is a confusion about setting protocol and cipher suite in integration between mod_cluster subsystem and wildfly-openssl:

OpenSSL 1.0.2h
This is the declaration of the called SSL_SESSION_get_id and this is the definition in ssl_sess.c
Conclusion
IMHO it wouldn't do any harm to check whether session ain't NULL before passing it on down to OpenSSL, but it is only the aftermath, not the original cause I suppose. It might be worth checking whether the bug is actually not simply in the mod_cluster java part, in calling org.wildfly.openssl.OpenSSLEngine with confused protocols/cipher suites.
