> When an OOM is thrown we do normally want the JVM to halt (assuming JVM flags state to), but this only happens in very specific cases (see CASSANDRA-15214 for more details).  Rather than relying on an allow list to convert to heap-oom, we should rely on an deny list; this way we handle every OOM thrown.
