title: Enabling JVM options with Java Web Start / JNLP
body: <p>I'm creating a Web Start application which would benefit from some of the newer JVM options (especially escape analysis, G1 garbage collector etc.)</p>
  
  <p>At the same time, I would like the application to work gracefully on older JVMs that do not support these options.</p>
  
  <p>Is there a good way of achieving this?</p>
