Logstash giving an error message which doesn't relate to configuration

Question

So, I'm attempting to setup Logstash working with the logstash-forwarder, but I'm having some issues. It doesn't seem like lumberjack actually starts up and listens on port 5000 (checked with netstat -anltp) and an error message, which doesn't seem to relate to my configuration is dumped in to the logstash log.

My Config file

input {
  lumberjack {
    port => 5000
    ssl_certificate => "/etc/ssl/star_server_com.crt"
    ssl_key => "/etc/ssl/server.key"
    type => "somelogs"
 }
}
output {
  elasticsearch_http {
    host => "haproxy.server.com"
    password => "a0fe9d5dedwedfacd240a25b0"
    user => "90765547wfefwefwee429f"
  }
}

Output from --configtest
