I am unsure what I am doing wrong. Any help is much appreciated:  
Logstash cmd: `[root@logstash bin]# ./logstash -f /etc/logstash/conf.d/rsyslog.conf --config.reload.automatic`

Followed the elastic guide here fine: [Parsing Logs with Logstash](https://www.elastic.co/guide/en/logstash/current/advanced-pipeline.html)  
Having problems with this Elastic Guide: [How To Centralize Logs with Rsyslog, Logstash, and Elasticsearch on Ubuntu 14.04](https://www.elastic.co/blog/how-to-centralize-logs-with-rsyslog-logstash-and-elasticsearch-on-ubuntu-14-04)  
I think my rsyslog is setup fine as I see the dev FW logs flowing in np. I believe I also have disabled the firewalls. These are dev sandboxes. I am using CentOS and the guide is for Ubuntu, but I believe it is fine/Ihave taken it into account.

As for the error, how do I fix Java Plugins? I am using Java 11 and it is installed fine I believe.
