title: Re launch JVM with bigger heap space
body: <p>I want to be able to execute the .Jar file, and if the heap space isn't set big enough, it should launch a new JVM with the same .Jar file, but set with a bigger heap space, and then close the first JVM and .Jar.</p>
  
  <p>I've tried using the ProcessBuilder, but I can't get it to work.</p>
  
  <p>It has to work cross platform.</p>
