title: Accessing java files from Eclipse source-bundle
body: <p>How do I access source code from an Eclipse/OSGI source-bundle?</p>
  
  <p>I use Maven/Tycho to produce the source bundles using the source-feature packaging. This works well for attaching the source for 3rd party development. They are referenced on the JAR as 'External location' for 'Java Source Attachement'. </p>
  
  <p>But how do I programmatically reach the source-bundle? Source bundles are not accessible as regular bundles, ie <code>Platform.getBundle('com.myplugin.source')</code>, and the source files are not accessible through the master bundle, ie 'com.myplugin' There's no reference in the plugin manifest headers either. Is there an Eclipse OSGI service that I should use? Any help would be appreciated.</p>
