PS. I had done something wrong with the hostname, now I'm back to
seeing the connection to the EC2 instance, but having the deployment
hang and eventually timeout.
Using the RMI debug properties sun.rmi.transport.logLevel=VERBOSE and
java.rmi.server.logCalls=true, this is all I can see on the server:
