Good advice. Thank you! I'll work on tuning IP tables so that only my other Cassandra nodes
can connect to mx4j. Good thing I caught this, I was just making sure JNA was working when
I saw this!

anything it thinks is HTTP.  This probably means your mx4j port is open to the public which
is a security issue.  This means anyone can e.g. delete all your data or stop your Cassandra
nodes.  You should make sure that all your Cassandra ports (at least) are firewalled so only
you and other nodes can connect.
