title: Eclipse plugin with JOGL - ClassNotFoundException
body: <p>I'm trying to create a eclipse plugin which uses JOGL to display some editor contents. <br>
  I packaged the required libraries (JOGL, Nativewindow and Gluegen) each into their own plugin and added all three plugins to the dependency of my editor plugin.<br>
  Now if I try to setup an OpenGL display and implement the <em>GLEventListener</em> I always get the following exception in the Eclipse error log upon loading the class which does the OpenGL calls:</p>
  
  <pre><code>java.lang.NoClassDefFoundError: com/jogamp/common/type/WriteCloneable
  </code></pre>
  
  <p>(full stack below) <br>
  I tracked down that class and it is located inside the Gluegen dependency and I can even open the class using the "Open type" dialog in eclipse and still eclipse doesn't seem to be able to find it.<br>
  I created the plugin project for the libraries using the "Plug-in from Existing JAR Archives" wizard inside Eclipse and I also double-checked the exported packages and they do contain the package which can't be found.<br>
  Now, does anyone know what I'm doing wrong? <br>
  <br>
  <br>
  Full stacktrace:</p>
