title: Eclipse Luna Doesn't Display JFrames
body: <p>I'm using a Mac and for some reason Eclipse Luna won't run any of my programs that use a <code>JFrame</code>. The problem persists on a fresh installation of Luna but using Juno or Kepler, the frame displays just fine. I'm also using Java 8. My classmates can run the same code fine on Kepler as well (Windows and Mac). It also runs fine if I run it through Terminal. I have no clue why Luna won't display <code>JFrame</code>s; does anyone know what the issue could possibly be?</p>
  
  <p>EDIT: Any program that runs through the console runs just fine.</p>
