title: Java - is it free?
body: <p>We've been using Java to build our enterprise software (not embedded) for years and redistributing the JRE to our customers freely.
  Recently Oracle representatives approached us at a tradeshow offering their services.
  After a couple of calls with our engineers they started claiming that we need to pay them for Java because our software is not "General Purpose".</p>
  
  <p>So, a few questions:</p>
  
  <ol>
  <li>Has anyone else encountered this?</li>
  <li>Has anyone switched to OpenJDK?</li>
  <li>Any other alternatives?</li>
  </ol>
  
  <p>Thanks in advance,</p>
  
  <p>Mark</p>
