title: Can Java 7 and Java 8 co-exist on OSX
body: <p>I've installed Java 8 for development purposes but now I'd like to use Java 7 again.</p>
  
  <p>How do I do this?</p>
  
  <p>It seems to be insanely difficult.</p>
  
  <p>Many thanks in advance.
  (I've tried using guigarage and that doesn't work)</p>
