title: Java Debugging Interface (com.sun.jdi) package missing in IntelliJ 2017.1-C
body: <p>I'm currently using IntelliJ IDEA Community Edition 2017.1 to work on a project that involves using a Greenfoot port (<a href="http://github.com/houbie/greenfoot" rel="nofollow noreferrer">GitHub</a>) that's optimized to use Groovy. The code is perfectly fine, but IntelliJ is telling me that com.sun.jdi doesn't exist. I am unsure as to how I might fix this. Any ideas?</p>
  
  <p>Sidenote: I don't know much about how JDI correlates with VM, which I suspect may have something to do with it.</p>
