title: W7 Logstash JRUBY Error
body: <p>I am new to the entire ELK Stack, and I am trying to set up Logstash. I followed all of the instructions (unzipping, setting up config file, starting Logstash). My setup is Windows 7, and my java version is 1.8.0_51.</p>
  
  <p>When I run the following command (pipeline.conf is my config file):</p>
  
  <pre><code>C:\Elastic\logstash-6.2.2\bin&gt;logstash -f pipeline.conf
  </code></pre>
  
  <p>I am getting the following error:</p>
  
  <pre><code>[ERROR] 2018-03-15 12:30:05.101 [main] Logstash - 
      java.lang.IllegalStateException: 
      org.jruby.exceptions.RaiseException:

      com.kenai.jffi.Foreign.getVersion()I  
          See http://jira.codehaus.org/browse/JRUBY-4583
  </code></pre>
  
  <p>Here is what my config file:</p>
  
  <pre><code>input {
      stdin {
  
      }
  }
  
  output {
      stdout {
          codec =&gt; rubydebug
      }
  }
  </code></pre>
  
  <p>Any help would be appreciated. <a href="http://jira.codehaus.org/browse/JRUBY-4583" rel="nofollow noreferrer">http://jira.codehaus.org/browse/JRUBY-4583</a> doesn't seem like a valid site. I have tried my exact process on a different machine, and Logstash works. I have been trying to look for a solution for about 2 days now. HELP PLS</p>
