----------------------------------------------
Summary: JVM segfault: mod_cluster subsystem cannot handle wildfly-openssl integration
Key: MODCLUSTER-554
URL: https://issues.jboss.org/browse/MODCLUSTER-554
Project: mod_cluster
Issue Type: Bug
Reporter: Michal Karm Babacek
Assignee: Stuart Douglas
Priority: Critical
h3. 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:
