title: How to use 3rd party library in Java9 module?
body: <p>I have some java9 module that uses 3rd party library that is not Java9 module, just a simple utility jar.</p>
  
  <p>However, the compiler complains that it can't find a package from my utility.</p>
  
  <p>What should I do in <code>module-info.java</code> to enable usage of my 3rd party library?</p>
