title: Is it safe to still use Java 6 and Eclipse Indigo for this application?
body: <p>We have an optimizer software written using Java and Optimj (<a href="https://en.wikipedia.org/wiki/OptimJ" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/OptimJ</a>), a tool that is tied to Eclipse.</p>
  
  <p>However, Optimj is no longer mantained and we are stuck in using Eclipse Indigo (last version supported) for  this reason. Also, that means we cannot use newer versions of Java for our application because they won't work with Eclipse Indigo.</p>
  
  <p>Our software is a standalone java program, totally developed by our team and runs in our servers, so we control 100% of the environment.</p>
  
  <p>The only outside connection to the software (via modbus/TCP) is done by means of VPN with the company's other sites, so they can have access to the results. Our application is not directly exposed to the WWW.</p>
  
  <p>In that situation, sticking to Eclipse Indigo and Java 6 poses any kind of security threat for us, so that a considerable investment in porting our optimization problem to another (considerably different) tool is justified?</p>
