Until one day a colleague of mine discovered an issue where a permission issue incorrectly reported as an invalid yaml file (complete with the supposedly offending key). Digging into the source code and trying to match up the message. I found that <a href="https://github.com/apache/cassandra/blob/06209037ea56b5a2a49615a99f1542d6ea1b2947/src/java/org/apache/cassandra/config/YamlConfigurationLoader.java#L128">we were handling YAMLException</a></p>
